Gentrification is a dynamic that emerges in poor urban areas when residential shifts, urban planning, and other phenomena affect the composition of a neighborhood. Urban gentrification often involves population migration as poor residents of a neighborhood are displaced. In a community undergoing gentrification, the average income increases and average family size decreases. This generally results in the displacement of the poorer, pre-gentrification residents, who are unable to pay increased rents, and property taxes, or afford real estate. Often old industrial buildings are converted to residences and shops. New businesses, which can afford increased commercial rent, cater to a more affluent base of consumers—further increasing the appeal to higher income migrants and decreasing the accessibility to the poor. Often, resident owners unable to pay the taxes are forced to sell their residences and move to a cheaper community.
Political action, either to promote or oppose the gentrification, is often the community's response against unintended economic eviction. However, local governments may favor gentrification because of the increased tax base associated with the new high-income residents, as well as because of other perceived benefits of moving poor people and rehabilitating deteriorated areas.

Origin and etymology
Gentrification is a multi-facted phenomenon that can be defined in different ways.
Historians say that gentrification took place in ancient Rome and in Roman Britain, where large villas were replacing small shops by the third century, A.D. The word gentrification derives from gentry—which comes from the Old French word genterise, "of gentle birth" (14th c.) and "people of gentle birth" (16th c.). In England, Landed gentry denoted the social class, consisting of gentlemen. An early reference to the word "gentrification" can be found in "Memoirs and Proceedings of the Manchester Literary & Philosophical Society", written in 1888. British sociologist Ruth Glass coined the term "gentrification" in 1964 to descibe the influx of middle-class people displacing lower-class worker residents in urban neighborhoods; her example was London, and its working-class districts such as Islington:
One by one, many of the working class neighbourhoods of London have been invaded by the middle-classes — upper and lower. Shabby, modest mews and cottages — two rooms up and two down — have been taken over, when their leases have expired, and have become elegant, expensive residences ... Once this process of 'gentrification' starts in a district it goes on rapidly, until all or most of the original working-class occupiers are displaced and the whole social character of the district is changed.
In the US, the Centers for Disease Control and Prevention report Health Effects of Gentrification defines the real estate concept of gentrification as "the transformation of neighbourhoods from low value to high value. This change has the potential to cause displacement of long-time residents and businesses ... when long-time or original neighborhood residents move from a gentrified area because of higher rents, mortgages, and property taxes. Gentrification is a housing, economic, and health issue that affects a community's history and culture and reduces social capital. It often shifts a neighbourhood's characteristics, e.g., racial-ethnic composition and household income, by adding new stores and resources in previously run-down neighbourhoods."
In the Brookings Institution report Dealing with Neighbourhood Change: A Primer on Gentrification and Policy Choices (2001), Maureen Kennedy and Paul Leonard say that "the term 'gentrification' is both imprecise and quite politically charged", suggesting its redefinition as "the process by which higher income households displace lower income residents of a neighbourhood, changing the essential character and flavour of that neighbourhood", so distinguishing it from the different socio-economic process of "neighbourhood (or urban) revitalization", although the terms are sometimes used interchangeably.
There are several approaches that attempt to explain the roots and the reasons behind the spread of gentrification. Bruce London and J. John Palen (1984) compiled a list of five explanations: (1) demographic-ecological, (2) sociocultural, (3) political-economical, (4) community networks, and (5) social movements.
The first theory, demographic-ecological, attempts to explain gentrification through the analysis of demographics: population, social organization, environment, and technology. This theory frequently refers to the growing number of people between the ages of 25 and 35 in the 1970s, or the baby boom generation. Because the number of people that sought housing increased, the demand for housing increased also. The supply could not keep up with the demand; therefore cities were "recycled" to meet such demands (London and Palen, 1984). The baby boomers in pursuit of housing were very different, demographically, from their house-hunting predecessors. They got married older, had fewer children, and the children they did have were born later. Women, both single and married, were entering the labour force at higher rates which led to an increase of dual wage-earner households. These households were typically composed of young, more affluent couples without children. Because these couples were child-free and were not concerned with the conditions of schools and playgrounds, they elected to live in the inner-city in close proximity to their jobs. These more affluent people usually had white-collar, not blue-collar jobs. Since these white-collar workers wanted to live closer to work, a neighbourhood with more white-collar jobs was more likely to be invaded; the relationship between administrative activity and invasion was positively correlated (London and Palen, 1984).
The second theory proposed by London and Palen is based on a sociocultural explanation of gentrification. This theory argues that values, sentiments, attitudes, ideas, beliefs, and choices should be used to explain and predict human behavior, not demographics, or "structural units of analysis" (i.e., characteristics of populations) (London and Palen, 1984). This analysis focuses on the changing attitudes, lifestyles, and values of the middle- and upper-middle-class of the 1970s. They were becoming more pro-urban than before, opting not to live in rural or even suburban areas anymore. These new pro-urban values were becoming more salient, and more and more people began moving into the cities. London and Palen refer to the first people to invade the cities as "urban pioneers." These urban pioneers demonstrated that the inner-city was an "appropriate" and "viable" place to live, resulting in what is called "inner city chic" (London and Palen, 1984). The opposing side of this argument is that dominant, or recurring, American values determine where people decide to live, not the changing values previously cited. This means that people choose to live in a gentrified area to restore it, not to alter it, because restoration is a "new way to realize old values" (London and Palen, 1984).
The third theoretical explanation of gentrification is political-economic and is divided into two approaches: traditional and Marxist. The traditional approach argues that economic and political factors have led to the invasion of the inner-city, hence the name political-economic. The changing political and legal climate of the 1950s and 60s (new civil rights legislation, antidiscrimination laws in housing and employment, and desegregation) had an "unanticipated" role in the gentrification of neighborhoods. A decrease in prejudice led to more blacks moving to the suburbs and whites no longer rejected the idea of moving to the city. The decreasing availability of suburban land and inflation in suburban housing costs also inspired the invasion of the cities. The Marxist approach denies the notion that the political and economic influences on gentrification are invisible, but are intentional. This theory claims that "powerful interest groups follow a policy of neglect of the inner city until such time as they become aware that policy changes could yield tremendous profits" (London and Palen, 1984). Once the inner city becomes a source of revenue, the powerless residents are displaced with little or no regard from the powerful.
The community-network approach is the fourth proposed by London and Palen. This views the community as an "interactive social group." Two perspectives are noted: community lost and community saved. The community lost perspective argues that the role of the neighborhood is becoming more limited due to technological advances in transportation and communication. This means that the small-scale, local community is being replaced with more large-scale, political and social organizations (Greer, 1962). The opposing side, the community saved side, argues that community activity increases when neighborhoods are gentrified because these neighborhoods are being revitalized.
The fifth and final approach is social movements. This theoretical approach is focused on the analysis of ideologically based movements, usually in terms of leader-follower relationships. Those who support gentrification are encouraged by leaders (successful urban pioneers, political-economic elites, land developers, lending institutions, and even the Federal government in some instances) to revive the inner-city. Those who are in opposition are the people who currently reside in the deteriorated areas. They develop countermovements in order to gain the power necessary to defend themselves against the movements of the elite. These countermovements can be unsuccessful, though. The people who support reviving neighborhoods are also members, and their voices are the ones that the gentrifiers tend to hear (London and Palen, 1984).
Two discrete, sociological theories explain and justify gentrification as an economic process (production-side theory) and as a social process (consumption-side theory) that occurs when the suburban gentry tire of the automobile-dependent urban sprawl style of life; thus, professionals, empty nest aged parents, and recent university graduates perceive the attractiveness of the city center — earlier abandoned during white flight — especially if the poor community possesses a transport hub and its architecture sustains the pedestrian traffic that allows the proper human relations impeded by (sub)urban sprawl.
Professor Smith and Marxist sociologists explain gentrification as a structural economic process; Ley explains gentrification as a natural outgrowth of increased professional employment in the central business district (CBD), and the creative sub-class's predilection for city living. "Liberal Ideology and the Post-Industrial City" (1980) describes and deconstructs the TEAM committee's effort to rendering Vancouver, BC, Canada, a "livable city". The investigators Rose, Beauregard, Mullins, Moore et al., who base themselves upon Ley's ideas, posit that "gentrifiers and their social and cultural characteristics [are] of crucial importance for an understanding of gentrification" — theoretical work Chris Hamnett criticized as insufficiently comprehensive, for not incorporating the "supply of dwellings and the role of developers [and] speculators in the process".
The production-side theory of urban gentrification derives from the work of human geographer Neil Smith, explaining gentrification as an economic process consequent to the fluctuating relationships among capital investments and the production of urban space. He asserts that restructuring of urban space is the visual component of a larger social, economic, and spacial restructuring of the contemporary capitalist economy. Smith summarizes the causes of gentrification into five main processes: suburbanization and the emergence of rent gap, deindustrialization, spatial centralization and decentralization of capital, falling profit and cyclical movement of capital, and changes in demographics and consumption patterns.
Suburbanization and Rent Gap
Suburban development derives from outward expansion of cities, often driven by sought profit and the availability of cheap land. This change in consumption causes a fall in inner city land prices, often resulting in poor upkeep and a neglect of repair for these properties by owners and landlords. The depressed land is then devalued, causing rent to be significantly cheaper than the potential rent that could be derived from the “best use” of the land while taking advantage of its central location. From this derives the Rent-gap Theory describing the disparity between "the actual capitalized ground rent (land price) of a plot of land given its present use, and the potential ground rent that might be gleaned under a 'higher and better' use."
The rent gap is fundamental to explaining gentrification as an economic process. When the gap is sufficiently wide, real estate developers, landlords, and other people with vested interests in the development of land perceive the potential profit to be derived from re-investing in inner-city properties and redeveloping them for new tenants. Thus, the development of a rent gap creates the opportunity for urban restructuring and gentrification.
The de-industrialization of cities in developed nations reduces the number of blue-collar jobs available to the urban working class as well as middle-wage jobs with the opportunity for advancement, creating lost investment capital needed to physically maintain the houses and buildings of the city. Abandoned industrial areas create availability for land for the rent gap process.
Spatial centralization and decentralization of capital
De-industrialization is often integral to the growth of a divided white collar employment, providing professional and management jobs that follow the spatial decentralization of the expanding world economy. However, somewhat counter-intuitively, globalization also is accompanied by spatial centralization of urban centers, mainly from the growth of the inner city as a base for headquarter and executive decision-making centers. This concentration can be attributed to the need for rapid decisions and information flow, which makes it favorable to have executive centers in close proximity to each other. Thus, the expanding effect of suburbanization as well as agglomeration to city centers can coexist. These simultaneous processes can translate to gentrification activities when professionals have a high demand to live near their executive workplaces in order to reduce decision-making time.
Falling profit and the cyclical movement of capital
This section of Smith’s theory attempts to describe the timing of the process of gentrification. At the end of a period of expansion for the economy, such as a boom in postwar suburbs, accumulation of capital leads to a falling rate of profit. It is then favorable to seek investment outside the industrial sphere to hold off onset of an economic crisis. By this time, the period of expansion has inevitably led to the creation of rent gap, providing opportunity for capital reinvestment in this surrounding environment.
Changes in demographic and consumption patterns
Smith emphasizes that demographic and life-style changes are more of an exhibition of the form of gentrification, rather than real factors behind gentrification. The aging baby-boomer population, greater participation of women in the workforce, and the changes in marriage and childrearing norms explain the appearance that gentrification takes, or as Smith says, “why we have proliferating quiche bars rather than Howard Johnson’s”.

In contrast to the production-side argument, the consumption-side theory of urban gentrification posits that the "socio-cultural characteristics and motives" of the gentrifiers are most important to understanding the gentrification of the post-industrial city. The changes in the structure of advanced capitalist cities with the shift from industrial to service-based economy were coupled with the expanding of a new middle class—one with a larger purchasing power than ever before. As such, human geographer David Ley posits a rehabilitated post-industrial city influenced by a this "new middle class."  The consumption theory contends that it is the demographics and consumption patterns of this “new middle class” that is responsible for gentrification.
The economic and cultural changes of the world in the 1960s have been attributed to these consumption changes. The antiauthoritarian protest movements of the young in the U.S., especially on college campuses, brought a new disdain for the “standardization of look-alike suburbs,”  as well as fueled a movement toward empowering freedom and establishing authenticity. In the postindustrial economy, the expansion of middle class jobs in inner cities came at the same time as many of the ideals of this movement. The process of gentrification stemmed as the new middle class, often with politically progressive ideals, was employed in the city and recognized not only the convenient commute of a city residence, but also the appeal towards the urban lifestyle as a means of opposing the “deception of the suburbanite.”
This new middle class was characterized by professionals with life pursuits expanded from traditional economistic focus. Gentrification provided a means for the ‘stylization of life’ and an expression of realized profit and social rank. Similarly, Michael Jager contended that the consumption pattern of the new middle class explains gentrification because of the new appeal of embracing the historical past as well as urban lifestyle and culture. The need of the middle class to express individualism from both the upper and lower classes was expressed though consumption, and specifically though the consumption of a house as an aesthetic object.
“This permanent tension on two fronts is evident in the architecture of gentrification: in the external restorations of the Victoriana, the middle classes express their candidature for the dominant classes; in its internal renovation work this class signifies its distance from the lower orders.” p. 154 
Gentrification, according to consumption theory, fulfills the desire for a space with social meaning for the middle class as well as the belief that it can only be found in older places because of a dissatisfaction with contemporary urbanism.
Gentrification is integral to the new economy of centralized, high-level services work — the "new urban economic core of banking and service activities that come to replace the older, typically manufacturing-oriented, core" that displaces middle-class retail businesses so they might be "replaced by upmarket boutiques and restaurants catering to new high-income urban élites". In the context of globalization, the city's importance is determined by its ability to function as a discrete socio-economic entity, given the lesser import of national borders, resulting in de-industrialized global cities and economic restructuring.
To wit, the American urban theorist John Friedman's seven-part theory posits a bifurcated service industry in world cities, composed of "a high percentage of professionals specialized in control functions and ... a vast army of low-skilled workers engaged in ... personal services ... [that] cater to the privileged classes, for those whose sake the world city primarily exists". The final three hypotheses detail (i) the increased immigration of low-skill labourers needed to support the privileged classes, (ii) the class and caste conflict consequent to the city's inability to support the poor people who are the service class, and (iii) the world city as a function of social class struggle — matters expanded by Saskia Sassen et al. The world city's inherent socio-economic inequality illustrates the causes of gentrification, reported in "Where Did They Go? The Decline of Middle-Income Neighborhoods in Metropolitan America" (2006) demonstrating geographical segregation by income in US cities, wherein middle-income (middle class) neighborhoods decline, while poor neighborhoods and rich neighborhoods remain stable.
As rent-gap theory would predict, one of the most visible changes the gentrification process brings is to the infrastructure of a neighborhood. Typically, areas to be gentrified are deteriorated and old, though structurally sound, and often have some obscure amenity such as a historical significance that attracts the potential gentrifiers. Gentry purchase and restore these houses, mostly for single-family homes. Another phenomenon is “loft conversion,” which rehabilitates mixed-use areas, often abandoned industrial buildings or run-down apartment buildings to housing for the incoming gentrifiers. While this upgrade of housing value is the superficial keynote to the gentrification process, there are a greater number of less-visible shifts the gentry bring with them into their new neighborhoods.

Displacement in the context of gentrification is defined in The Gentrification Reader as “forced disenfranchisement of poor and working class people from the spaces and places in which they have legitimate social and historical claims."  It is one of the must studied negative aspects of gentrification, yet its nature has provided researchers with many prohibitive barriers to obtaining accurate and reliable data, much of which is more focused on the gentrifiers than those who are displaced by the process.
What is generally agreed upon, however, is that those displaced are primarily minority, elderly, and transient groups, and they are nearly always driven out in areas where gentrification occurs. Studies have also shown that there seem to be two waves of displacement of these original residents. In the early stages, renters are largely driven out because of the changing incentives of landlords. With the rising interest in a particular neighborhood, they have no motive to retain their current tenants over the new, more affluent rent seekers. As the process continues, owners of single residential units are strained with the surge in property values that translates to increased tax assessments. Often their incomes cannot continue to cover these increased living costs. Those who are ‘gentrified’ not only lack the economic resources to compete with these changes, but stereotypically lack political power, are easily exploited by landlords and developers, and eventually are simply forced to leave due to these inabilities to resist the gentrification process.
Many of the social effects of gentrification have been based on extensive theories about how socioeconomic status of an individual's neighborhood will shape one's behavior and future. These studies have prompted "social mix policies" to be widely adopted by governments to promote the process and its positive effects, such as lessening the strain on public resources, that are associated with de-concentrating poverty. However, more specific research has shown that gentrification does not necessarily correlate with "social mixing," and that the effects of the new composition of a gentrified neighborhood can both weaken as well as strengthen community cohesion 
Housing confers social status, and the changing norms that accompany gentrification translate to a changing social hierarchy. The process of gentrification mixes people of different socioeconomic strata, thereby congregating a variety of expectations and social norms. The change gentrification brings in class distinction also has been shown to contribute to residential polarization by income, education, household composition, and race. It conveys a social rise that brings new standards in consumption, particularly in the form of excess and superfluity, to the area that were not held by the pre-existing residents. These differing norms can lead to conflict, which potentially serves to divide changing communities. Often this comes at a larger social cost to the original residents of the gentrified area whose displacement is met with little concern from the gentry or the government. Clashes that result in increased police surveillance, for example, would more adversely affect young minorities who are also more likely to be the original residents of the area.
There is also evidence to support that gentrification can strengthen and stabilize when there is a consensus about a community's objectives. Gentrifiers with an organized presence in deteriorated neighborhoods can demand and receive better resources. A characteristic example is a combined community effort to win historic district designation for the neighborhood, a phenomenon that is often linked to gentrification activity. Gentry can exert a peer influence on neighbors to take action against crime, which can lead to even more price increases in changing neighborhoods when crime rates drop and optimism for the area's future climbs.
The economic changes that occur as a community goes through gentrification are often favorable for local governments. Affluent gentrifiers expand the local tax base as well as support local shops and businesses, a large part of why the process is frequently alluded to in urban policies. The decrease in vacancy rates and increase in property value that accompany the process can work to stabilize a previously struggling community, restoring interest in inner-city life as a residential option alongside the suburbs. These changes can create positive feedback as well, encouraging other forms of development of the area that promote general economic growth.
Home ownership is a significant variable when it comes to economic impacts of gentrification. People who own their homes are much more able to gain financial benefits of gentrification than those who rent their houses and can be displaced without much compensation.
Just as critical to the gentrification process as creating a favorable environment is the availability of the ‘gentry,’ or those who will be first-stage gentrifiers. The typical gentrifiers are affluent and have a professional-level, service industry jobs, many of which involve self-employment  Therefore, they are willing and able to take the investment risk in the housing market. Often they are single people or young couples without kids who lack demand for good schools. Gentrifiers are likely searching for inexpensive housing close to the workplace and often already reside in the inner city, sometimes for educational reasons, and do not want to make the move to suburbia. Thus, gentrification is not so much the result of a return to the inner city but is more of a positive action to remain there.
The stereotypical gentrifiers also have shared consumer preferences and favor a largely consumerist culture. This requires the rapid expansion of trendy restaurant, shopping, and entertainment spheres that often accompany the gentrification process. Holcomb and Beauregard described these groups as those who are “attracted by low prices and toleration of an unconventional lifestyle.” 
An interesting find from research on those who participate and initiate the gentrification process, the “marginal gentrifiers” as referred to by Tim Butler, is that they become marginalized by the expansion of the process. Research has also shown subgroups of gentrifiers that fall outside of these stereotypes. Two important ones are women, typically single mothers, as well as gay people who are typically men.
Women’s participation in the labor force has risen dramatically in the past 50 years, translating to an expansion of women with higher incomes and opportunities to invest. Smith suggests this group “represents a reservoir of potential gentrifiers."  The larger percentages of highly educated women who postpone marriage and childrearing also play into this theory, as well as the fact that residence in the inner city can give women access to the well-paid jobs and networking, something that is becoming increasingly common.
There are also theories that suggest the inner-city lifestyle is important for women with children because of the network of support it provides for childcare. This attracts specifically single women with children to the inner-city over suburban areas, often as “marginal gentrifiers,” for the city can offer an easier solution to combining paid and unpaid labor. Inner city concentration increases the efficiency of commodities working mothers need by minimizing time constraints between multiple jobs, childcare, and markets, for example.
Gay and lesbian people
The Queen Anne-style Beath-Dickey House in Atlanta's Inman Park, whose restoration in 1969 sparked gentrification in Atlanta
Manuel Castells's seminal work about gay men as "gentrifiers" in San Francisco, California, is the most famous case study of sexuality and gentrification. His work shows that "many gays were single men, did not have to raise a family, were young, and connected to a relatively prosperous service economy" is a pattern replicated in other North American cities.
Castells’ study reflected three specific trends of the gay gentrifiers of San Francisco. The primary means of gentrification by gays of the city happened when less affluent gay men bought housing as a collective, then renovated the residence themselves. Less common but also observed was the influence of affluent gay professional men, as well as gay realtors and interior decorators who made a career out of renovating deteriorated housing and selling for profit.
Gentrification is not only dominated by gay men, for gentrification movements in neighborhoods have been led by lesbians as well. Park Slope in New York City is one of the most famous examples. Lesbian communities correlated with the expansion of the women’s movement and the attraction of gentrification as ‘sweat equity,’ as well as the strong influence of lesbian social networking power.

Phillip Clay’s two-stage model of gentrification places artists as prototypical stage one or “marginal” gentrifiers. The National Endowment for the Arts did a study that linked the proportion of employed artists to the rate of inner city gentrification across a number of U.S. cities. Artists will typically accept the risks of rehabilitating deteriorated property, as well as have the time, skill, and ability to carry out these extensive renovations. Ley states that the artist’s critique of everyday life and search for meaning and renewal are what make them early recruits for gentrification.
The identity residence in the inner city provides is important for the gentrifier, and this is particularly so in the artists’ case. Their cultural emancipation from the bourgeois makes the central city an appealing alternative to distance themselves from the conformity and mundaneness attributed to suburban life. They are quintessential city people, and the city is often a functional choice as well, for city life has advantages that include cheap space, connections to costumers, and a closer proximity to a downtown art scene, all of which are more likely to be limited in a suburban setting. Ley’s research cites a quote from a Vancouver printmaker talking about the importance of inner city life to an artist, that it has, “energy, intensity, hard to specify but hard to do without” (1996).
Ironically, these attributes that make artists characteristic marginal gentrifiers form the same foundations for their isolation as the gentrification process matures. The later stages of the process generate an influx of more affluent, “yuppie” residents. As the bohemian character of the community grows, it appeals "not only to committed participants, but also to sporadic consumers," and the rising property values that accompany this migration often lead to the eventual pushing out of the artists that began the movement in the first place. Sharon Zukin’s study of SoHo in Manhattan, NYC was one of the most famous cases of this phenomenon. Throughout the 1960s and 1970s, Manhattan lofts in SoHo were converted en masse into housing for artists and hippies, and then their sub-culture followers.
To counter the gentrification of their mixed-populace communities, residents formally organized themselves to develop the necessary socio-political strategies required to retain local affordable housing; many such organizations arose in the 1960s, and used the pragmatic tactics advocated by Saul Alinsky (1909–1972). In the late 1960s, the Young Lords Chicago street gang — who were politically active in the then-Puerto Rican neighborhood of Lincoln Park — practiced the direct-action techniques of sit-in protests and occupying vacant community lands. In Miami, Florida, the Liberty City community organization "Take Back the Land" seized empty lands and built the Umoja Village shantytown for the community's homeless people in October 2006. Like-wise, other communities established community development corporations that include the residents in actively developing their neighborhoods.
Direct action and sabotage
When wealthy people move into low-income working-class neighborhoods, the resulting class conflict sometimes involves vandalism and arson targeting the property of the gentrifiers. During the dot-com boom of the late 1990s, the gentrification of San Francisco's predominantly working class Mission District led some long-term neighborhood residents to create what they called the "Mission Yuppie Eradication Project.(image)" This group allegedly destroyed property and called for property destruction as part of a strategy to oppose gentrification. Their activities drew hostile responses from the San Francisco Police Department, real estate interests, and "work-within-the-system" housing activists.
Meibion Glyndŵr (Welsh: Sons of Glyndŵr) was a Welsh nationalist movement violently opposed to the loss of Welsh culture and language. They were formed in response to the housing crisis precipitated by large numbers of second homes being bought by the English which had increased house prices beyond the means of many locals. The group were responsible for setting fire to English-owned holiday homes in Wales from 1979 to the mid-1990s. In the first wave of attacks, eight holiday homes were destroyed in a month, and in 1980, Welsh Police carried out a series of raids in Operation Tân. Within the next ten years, some 220 properties were damaged by the campaign. Since the mid-1990s the group has been inactive and Welsh nationalist violence has ceased.
The gentrification of a mixed-income community raises housing affordability to the fore of the community's politics. Cities, municipalities, and counties have countered gentrification with inclusionary zoning (inclusionary housing) ordinances requiring the apportionment of some new housing for the community's original low- and moderate-income residents. Because inclusionary zoning is a new social concept, there are few reports qualifying its effective or ineffective limitation of gentrification. In Los Angeles, California, inclusionary zoning apparently accelerated gentrification, as older, unprofitable buildings were razed and replaced with mostly high-rent housing, and a small percentage of affordable housing; the net result was less affordable housing.
Zoning ordinances and other urban planning tools can be used to recognize and support local business and industries. This can include requiring developers to continue with a current commercial tenant or offering development incentives for keeping existing businesses, as well as creating and maintaining industrial zones. Designing zoning to allow new housing near to a commercial corridor but not on top of it increases foot traffic to local businesses without redeveloping them. Businesses can become more stable by securing long-term commercial leases.
Although developers may recognize value in responding to living patterns, extensive zoning policies often prevent affordable homes from being constructed within urban development. Due to urban density restrictions, rezoning for residential development within urban living areas is difficult, which forces the builder and the market into urban sprawl and propagates the energy inefficiencies that come with distance from urban centers. In a recent example of restrictive urban zoning requirements, Arcadia Development Co. was prevented from rezoning a parcel for residential development in an urban setting within the city of Morgan Hill, California. With limitations established in the interest of public welfare, a density restriction was applied solely to Arcadia Development Co.’s parcel of development, excluding any planned residential expansion.

Besides the informal, economic eviction of the community's poorer residents, another detrimental aspect of gentrification is its negative economic impact upon the community's commerce. Often, a neighborhood in mid-gentrification has marketable artist colony cachet that renders it popular, because of its nightlife, light industry, and arts-and-crafts businesses. In the event, the (ex-suburban) new-resident gentry complain to local government about the artist-colony "noise", pressuring the authorities to impose financially onerous noise-limitation requirements that eventually (and informally) evict said urban pioneer businesses. In New Zealand, this practice is called reverse sensitivity, a novel approach whereby the local gentry use land-use zones to identify feasible "reverse sensitivity" matters, i.e., "noisy neighbors" who then must meet zoning requirements mitigating their noise, or leave.

Because land speculation tends to raise property values, removing real estate (houses, buildings, land) from the open market stabilises property values, and thereby prevents the economic eviction of the community's poorer residents. The most common, formal legal mechanism for such stability is the community land trust; moreover, many inclusionary zoning ordinances formally place the "inclusionary" housing units in a land trust.
In jurisdictions where local or national government has these powers, there may be rent control regulations. Rent control restricts the rent that can be charged, so that incumbent tenants are not forced out by rising rents. If applicable to private landlords, it is a disincentive to speculating with property values, reduces the incidence of dwellings left empty, and limits availability of housing for new residents. If the law does not restrict the rent charged for dwellings that come onto the rental market (formerly owner-occupied or new build), rents in an area can still increase. The cities of southwestern Santa Monica and eastern West Hollywood in California, United States gentrified despite — or perhaps, because of — rent control.
Occasionally, a housing black market develops, wherein landlords withdraw houses and apartments from the market, making them available only upon payment of additional key money, fees, or bribes — thus undermining the rent control law. Many such laws allow "vacancy decontrol", releasing a dwelling from rent control upon the tenant's leaving — resulting in steady losses of rent-controlled housing, ultimately rendering rent control laws ineffective in communities with a high rate of resident turnover. In other cases social housing owned by local authorities may be sold to tenants and then sold on. Vacancy decontrol encourages landlords to find ways of shortening their residents' tenure, most aggressively through landlord harassment. To strengthen the rent control laws of New York City, New York, housing advocates active in rent control in New York are attempting to repeal the vacancy decontrol clauses of rent control laws. The state of Massachusetts abolished rent control in 1994; afterwards, rents rose, accelerating the pace of Boston's gentrification; however, the laws protected few apartments, and confounding factors, such as a strong economy, had already been raising housing and rental prices.
Support and Criticism
Gentrification has been substantially advocated by local governments, often in the form of ‘urban restructuring’ policies. Goals of these policies include dispersing low-income residents out of the inner city and into the suburbs as well as redeveloping the city to foster mobility between both the central city and suburbia as residential options  The strain on public resources that often accompanies concentrated poverty is relaxed by the gentrification process, a benefit of changed social makeup that is favorable for the local state. The expanded tax base and increased local retail support as effects of gentrification are favorable changes for the city in an economic sense as well. However, the better part of the gentrification process has happened without much government aid. Rehabilitation movements have been largely successful at restoring the plentiful supply of old and deteriorated housing that is readily available in inner cities. This rehabilitation can be seen as a superior alternative to expansion, for the location of the central city offers an intact infrastructure that should be taken advantage of: streets, public transportation, and other urban facilities. There is also evidence that these rehabilitation movements avoid displacement of the poor, who face the larger problem of disinvestment in concentrated poverty. Figures from surveys in 1990 showed that recently moved residents who could be considered "displaced" numbered only 5.47%, a decidedly small figure. Furthermore, the changed perception of the central city that is encouraged by gentrification can be healthy for resource-deprived communities who have previously been largely ignored.
The dominating argument against gentrification lies in the moral obligation to inhibit the adverse effects the process can have on gentrified communities. “[G]entrification is just the fin above the water. Below is the rest of the shark: a new American economy in which most of us will be poorer, a few will be far richer, and everything will be faster, more homogenous and more controlled or controllable” –Rebecca Solnit (2000) 
Chester Hartman asserts that a “right to displace” in today’s society is an overwhelming fact; residential property owners can drive out non-owners in some way or another. A change of residence that is forced upon people who lack resources to cope is detrimental to individuals and families and has social costs. Studies have shown that those who are displaced are disproportionately nonwhite, elderly, poor and large households. Displacement forces them into a biased housing market, where they are often forced to settle with more expensive and less adequate space. Hartman argues that this should be met with a “right to stay put,” and that measures protecting these marginal groups from gentrification should be put into place.
Gentrification-increased property values are a positive economic development for cities when tax revenues increase consequent to increased property values, however existing residents experience the change as increased property taxes. The increased taxes force many original property owners to either pay and stay (via higher rents for their tenants) or to sell and leave the gentrifying community. In gentrifying communities without strong rent-control laws poor residents are informally evicted when they cannot afford the increased rents. As a result, such economically limited people usually oppose gentrification.
There is also the argument that gentrification reduces the social capital of the area it affects. Communities have strong ties to the history and culture of their neighborhood, and causing its dispersal can have detrimental costs. The Center for Disease Control and Prevention has a webpage discussing adverse effects gentrification has on health, and provides a list of policies that would inhibit gentrification in order to prevent these impacts.
Inner London, England
Gentrification is not a new phenomenon in Britain; in ancient Rome the shop-free forum was developed during the Roman Republican period, and in second- and third-century cities in Roman Britain there is evidence of small shops being replaced by large villas.
King's College London academic Loretta Lees reported that much of inner-city London was undergoing "super-gentrification", where "a new group of super-wealthy professionals, working in the City of London, is slowly imposing its mark on this Inner London housing market, in a way that differentiates it, and them, from traditional gentrifiers, and from the traditional urban upper classes ... Super-gentrification is quite different from the classical version of gentrification. It's of a higher economic order; you need a much higher salary and bonuses to live in Barnsbury" (some two miles north of central London).
Barnsbury was built around 1820, as a middle-class suburb, but after the Second World War (1939–1945), people moved to the suburbs. The upper and middle classes were fleeing from the working class residents of London; the modern railway allowed it. At war's end, the great housing demand rendered Barnsbury the place of cheap housing, where most people shared accommodation. In the late 1950s and early 1960s, people moving into the area had to finance house renovations with their money, because banks rarely financed loans for Barnsbury. Moreover, the rehabilitating spark was The 1959 Housing Purchase and Housing Act, investing £100 million to rehabilitating old properties and infrastructure. Resultantly, the principal population influx occurred between 1961 and 1975; the UK Census reports that "between the years of 1961 and 1981, owner-occupation increased from 7 to 19 per cent, furnished rentals declined from 14 to 7 per cent, and unfurnished rentals declined from 61 to 6 per cent"; another example of urban gentrification is the super-gentrification, in the 1990s, of the neighbouring working-class London Borough of Islington, where Prime minister Tony Blair moved upon his election in 1997.
Other gentrified areas of London include Highbury, Canonbury, Newington Green, Shoreditch, Hoxton, Camden Town, Kentish Town, Crouch End, Fulham, Notting Hill, Clapham, Southwark, Bermondsey, Isle of Dogs, Kennington, Battersea, King's Cross, Pimlico, Dalston, Shepherds Bush, Hackney
From a market standpoint, there are two main requirements that are met by the U.S. cities that undergo substantial effects of gentrification. These are: an excess supply of deteriorated housing in central areas, as well as a considerable growth in the availability of professional jobs located in central business districts. These conditions have been met in the U.S. largely as a result of suburbanization and other postindustrial phenomena.
Starting in the 1960s and 1970s, U.S. industry has created a surplus of housing units as construction of new homes has far surpassed the rate of national household growth. However, the market forces that are dictated by an excess supply cannot fully explain the geographical specificity of gentrification in the U.S., for there are many large cities that meet this requirement and have not exhibited gentrification. The missing link is another factor that can be explained by particular, necessary demand forces. In U.S. cities in the time period from 1970-1978, growth of the central business district at around 20% did not dictate conditions for gentrification, while growth at or above 33% yielded appreciably larger gentrification activity. Succinctly, central business district growth will activate gentrification in the presence of a surplus in the inner city housing market.
In the U.S., these conditions were generated by the economic transition from manufacturing to post-industrial service economies. The post-World War II economy experienced a service revolution, which created white-collar jobs and larger opportunities for women in the work force, as well as an expansion in the importance of centralized administrative and cooperate activities. This increased the demand for inner city residences, which were readily available cheaply after much of the movement towards central city abandonment of the 1950s. The coupling of these movements is what became the trigger for the expansive gentrification of U.S. cities, including Atlanta, Boston, Philadelphia, and Washington, D.C. 
Bungalows in Atlanta's Inman Park neighborhood, United States.
Main article: Gentrification in Atlanta
Gentrification in Atlanta has been taking place in its inner-city neighborhoods since the 1970s. Many of Atlanta's neighborhoods experienced the urban flight that affected other major American cities in the 20th century, causing the decline of once upper and upper-middle-class east side neighborhoods. In the 1970s, after neighborhood opposition blocked two freeways from being built through the east side, its neighborhoods such as Inman Park and Virginia-Highland became the starting point for the city's gentrification wave, first becoming affordable neighborhoods attracting young people, and by 2000 having become relatively affluent areas attracting people from across Metro Atlanta to their upscale shops and restaurants. In the 1990s and 2000s, gentrification expanded into other parts of Atlanta, spreading throughout the historic streetcar suburbs east of Downtown and Midtown, mostly areas that had long had black majorities such as the Old Fourth Ward, Kirkwood, Reynoldstown and Edgewood. On the western side of the city, once-industrial West Midtown became into a vibrant neighborhood full of residential lofts and a nexus of the arts, restaurants, and home furnishings. Gentrification by young African Americans was also taking place in the 1990s in southwest Atlanta neighborhoods, but has been hindered by the Great Recession. The BeltLine trail construction is expected to bring further gentrification in the neighborhoods alongside which it runs. Concerns about displacement of existing working-class black residents by increasing numbers of more affluent whites moving in are expressed by author Nathan McCall in his novel Them, in The Atlanta Progressive News, and in the documentary The Atlanta Way.
The city of Boston, Massachusetts, has seen several neighborhoods undergo significant periods of urban renewal, specifically during the 1960s to the 1980s. Called “turbo-gentrification” by sociologist Alan Wolfe, particular areas of study of the process have been done in South End, Bay Village, and West Cambridge. In Boston's North End, the destruction of the noisy Central Artery elevated highway attracted younger, more affluent new residents, in place of the traditional Italian immigrant culture. The gentrification of the Beacon Hill area was also the object of focus of the New York Times in 1999; Carey Goldberg wrote, “from shabby gentility to $3 million price tags on town houses without garages that allow passers-by on snowy days the unusual sight of a billionaire or two clearing off their cars.” Houses in the area were being sold for $100,000 in 1970, and first entered the 1 million range in 1984. Other neighborhoods of the Boston area show similar statistics on the influx of affluent residents to previously deteriorated housing areas, as well as the spike in property values and political and social activity for new residents that are often distinctive of the gentrification process.
In the early 1960s, Boston’s South End had a great many characteristics of a neighborhood that is prime for gentrification. The available housing was architecturally sound and unique row houses in a location with high accessibility to urban transport services, while surrounded by small squares and parks. A majority of the area had also been designated a National Historic District.
South End became deteriorated by the 1960s. Many of the row houses had been converted to cheap apartments, and the neighborhood was plagued by dominant, visible poverty. The majority of the residents were working-class individuals and families with a significant need for public housing and other social services. The situation was recognized by local governments as unfavorable, and in 1960 became the target of an urban renewal effort of the city.
The construction of the Prudential Tower complex that was finished in 1964 along the northwest border of South End was a spark for this urban-renewal effort and the gentrification process for the area that surrounded it. The complex increased job availability in the area, and the cheap housing stock of South End began to attract a new wave of residents. The next 15 years saw an influx of predominantly affluent, young professionals who purchased and renovated houses in South End. Unfortunately, tension characterized the relationship between these new residents and the previous residents of the neighborhood. Clashes in the vision for the area’s future was the main source of conflict. The previous, poorer residents, contended that “renewal” should focus on bettering the plight of South End’s poor, while new, middle-class residents heavily favored private market investment opportunities and shunned efforts such as subsidized housing with the belief that they would flood the market and raise personal security concerns.
The late 1940s was a transition for the area from primarily families with children as residents to a population dominated by both retired residents and transient renters. The 2–3 story brick row houses were largely converted to low-cost lodging houses, and the neighborhood came to be described as “blighted” and “down at heel.” This deterioration was largely blamed on the transient population.
The year 1957 began the upgrading of what was to become Bay Village, and these changes were mainly attributed to new artists and gay men moving to the area. These “marginal” gentrifiers made significant efforts towards superficial beautification as well as rehabilitation of their new homes, setting the stage for realtors to promote the rising value of the area.
Of the homebuyers in Bay Village from 1957-1975, 92% had careers as white-collar professionals. 42% of these homebuyers were 25–34 years old. The majority of them were highly educated and moving from a previous residence in the city, suggesting ties to an urban-based educational institution. The reasons new homebuyers gave for their choice of residence in Bay Village was largely attributed to its proximity to downtown, as well as an appreciation for city life over that of suburbia (Pattison 1977).
The development and gentrification of West Cambridge began in 1960 as the resident population began to shift away from the traditional majority of working class Irish immigrants. The period of 1960-1975 had large shifts in homebuyer demographics comparable to that experienced by Bay Village. Professional occupations were overrepresented in homebuyers during this 15-year period, as well as the age group of 25–34 years old. Residents reported a visible lack of social ties between new homebuyers and the original residents. However, displacement was not cited as a problem because the primary reason of housing sale remained the death of the sole-surviving member of the household or the death of a spouse.
Researcher Timothy Pattison divided the gentrification process of West Cambridge into two main stages. Stage one began with various architects and architectural students who were attracted to the affordability of the neighborhood. The renovations efforts these “marginal” gentrifiers undertook seemed to spark a new interest in the area, perhaps as word of the cheap land spread to the wider student community.
The Peabody Schools also served as an enticing factor for the new gentrifiers for both stages of new homebuyers. Stage two of the process brought more architects to the area as well as non-architect professionals, often employed at a university institution. The buyers in stage two cited Peabody schools and the socioeconomic mix of the neighborhood as primary reasons for their residential choice, as well as a desire to avoid job commutes and a disenchantment with the suburban life.
Philadelphia: Darien Street
Gentrification Amid Urban Decline: Strategies for America's Older Cities, by Michael Lang, reports the process and impact (social, economic, cultural) of gentrification. In particular, it focuses on the section of Darien Street (a north-south street running intermittently from South to North Philadelphia) which is essentially an alley in the populous Bella Vista neighborhood. That part of Darien Street was a "back street", because it does not connect to any of the city's main arteries and was unpaved for most of its existence.
In its early days, this area of Darien Street housed only Italian families, however, after the Second World War (1939–1945), when the municipal government spoke of building a cross-town highway, the families moved out. Most of the houses date from 1885 (built for the artisans and craftsmen who worked and lived in the area), but, when the Italian Americans moved out, the community's low-rent houses went to poor African American families. Moreover, by the early 1970s, blighted Darien Street was at its lowest point as a community, because the houses held little property value, many were abandoned, having broken heaters and collapsed roofs, et cetera. Furthermore, the houses were very small — approximately 15 feet (4.6 m) wide and 15 feet (4.6 m) deep, each had three one-room stories (locally known, and still currently advertised as a "Trinity" style house,) and the largest yard was 8 feet (2.4 m) deep. Despite the decay, Darien Street remained charmed with European echoes, each house was architecturally different, contributing to the street's community character; children were safe, there was no car traffic. The closeness of the houses generated a closely knit community located just to the south of Center City, an inexpensive residential neighborhood a short distance from the city-life amenities of Philadelphia; the city government did not hesitate to rehabilitate it.
The gentrification began in 1977; the first house rehabilitated was a corner property that a school teacher re-modeled and occupied. The next years featured (mostly) white middle-class men moving into the abandoned houses; the first displacement of original Darien Street residents occurred in 1979. Two years later, five of seven families had been economically evicted with inflated housing prices; the two remaining families were renters, expecting eventual displacement. In five years, from 1977 to 1982, the gentrification of Darien Street reduced the original population from seven black households and one white household, to two black households and eleven white households. The average rent increased 488 per cent — from $85 to $500 a month; by 1981, a house bought for $5,000 sold for $35,000. Of the five black households displaced, three found better houses within two blocks of their original residence, one family left Pennsylvania, and one family moved into a public housing apartment building five blocks from Darien Street. The benefits of the Darien Street gentrification included increased property tax revenues and better-quality housing. The principal detriment was residential displacement via higher priced housing.
Gentrification in Washington, DC is one of the most studied examples of the process, as well as one of the most extreme. The process in the U Street Corridor and other downtown areas has recently become a major issue, and the resulting changes have led to African-Americans dropping from a majority to a minority of the population, as they move out and middle-class whites and Asians have moved in.
D.C. is one of the top three cities with the most pronounced capital flow into its “core” neighborhoods, a measurement that has been used to detect areas experiencing gentrification. Researcher Franklin James found that, of these core areas, Capitol Hill was significantly revitalized during the decade of 1960-1970, and by the end of the decade this revitalization had extended outward in a ring around this core area. Dennis Gale studied these ‘Revitalization Areas,’ which include Dupont Circle, Adams Morgan, and Capitol Hill neighborhoods, and as compared to the rest of the district found that these areas were experiencing a faster rate of depopulation in the 1970s than the surrounding areas. U.S. census data show that in the Revitalization Areas, the percent of population with four or more years of college education rose from 24% in 1970 to 47% in 1980, as opposed to an increase of 21% to 24% for the remaining areas of D.C. Additionally, Gale’s data show in 1970 that 73% of the residents living in the Revitalization Areas had been residents since 1965, as opposed to only 66% of the residents living there in 1975 had been residents of the area in 1970 as well.
The gentrification during this time period resulted in a significant problem of displacement for marginalized D.C. residents in the 1970s. A decrease in the stock of affordable housing for needy households as well as nonsubsidized housing for low-income workers has had a burdensome effect on individuals and families.
As a result of gentrification, however, Washington, D.C.'s safety has improved drastically. In the early 1990s, the city had an average of 500 homicides a year; by 2012, the rate has dropped by more than 80% to about 100. Many of the city's poorer residents were pushed out to Prince George's County, MD. Prince George's County saw a huge spark of violent crimes in 2008 and 2009, but the rate has improved since then.
As of 2011, gentrification in Canada has proceeded quickly in older and denser cities such as Montreal, Toronto, Ottawa and Vancouver, but has barely begun in places such as Calgary, Edmonton, or Winnipeg, where suburban expansion is still the primary type of growth. Since Canada did not experience the same degree of "white flight" as in the U.S. during the 1960s and 70s, the term "gentrification" in Canada is not synonymous with prodominent-white people moving into the neighbourhoods of people of colour, as it is in the United States. In fact in Toronto and Vancouver recent Asian immigrants and foreign buyers are also major purchasers of downtown housing, leading to a major housing price spike in those cities in 2011.
In Paris, most poorer neighborhoods in the east have seen rising prices and the arrival of many wealthy residents. However, the process is mitigated by social housing and most cities tend to favor "social mixity"; that is, having both low and high-income residents in the same neighborhoods. But in practice, social housings do not cater to the poorest segment of the population, most residents of social dwellings are from the low-end of the middle class. As a result, a lot of poor people have been forced to go first in the close suburbs (1970 to 2000) and then more and more to remote "periurban areas" where public transport is almost inexistent. The close suburbs (Saint Denis, Aubervilliers, ...) are now in early stage of gentrification although still poor. A lot of high profile companies offering well-paying jobs have moved near Saint-Denis and new real-estate programs are underway to provide living areas close to the new jobs.
On the other side, the eviction of the poorest people to periurban areas since 2000 has been considered by many analysts[who?] as the main cause for the rise of far-right national front. When the poor lived in the close suburbs, their problems were very visible to the wealthy population and the politics cared even if that was not enough to avoid the 2005 riots in Paris suburbs. But the periurban population and its problem is mainly "invisible" and in the recent[when?] presidential campaign, these people have labelled themselves "les invisibles". Many of them fled both rising costs in Paris and close suburbs and an insecure and ugly environment to live in small houses in the countryside but close to the city. But they did not factor in the huge financial and human cost of having up to four hours transportation every day. Since then, a lot has been invested in the close suburbs (with new public transports set to open and urban renewal programs) they fled, but almost nobody cares of these "invisible" plots of land. Since the close suburbs are now mostly inhabited by immigrants, these people have a strong resentment against immigration: They feel everything is done for new immigrants but nothing for the "white" population. This has been first documented in the book Plaidoyer pour une gauche populaire by think-tank Terra-Nova which had a major influence on all contestants in the presidential election (and at least, Sarkozy, François Hollande and Marine Le Pen). This electorate voted overwhelmingly in favor of Marine Le Pen and Sarkozy while the city centers and close suburbs voted overwhelmingly for François Hollande.
Most major metropolises in France follow the same pattern with a belt of periurban development about 30 to 80 kilometers of the center where a lot of poor people moved in and are now trapped by rising fuel costs. These communities have been disrupted by the arrival of new people and already suffered of high unemployment due to the dwindling numbers of industrial jobs.
In smaller cities, the suburbs are still the principal place where people live and the center is more and more akin to a commercial estate where a lot of commercial activities take place but where few people live.
Cape Town, South Africa
The Bo-Kaap pocket of Cape Town nestles against the slopes of Signal Hill. It has traditionally been occupied by members of South Africa's minority, mainly Muslim, Cape Malay community. These descendants of artisans and political captives, brought to the Cape as early as the 18th century as slaves and indentured workers, were housed in small barrack-like abodes on what used to be the outskirts of town. As the city limits increased, property in the Bo-Kaap became very sought after, not only for its location but also for its picturesque cobble-streets and narrow avenues. Increasingly, this close-knit community is "facing a slow dissolution of its distinctive character as wealthy outsiders move into the suburb to snap up homes in the City Bowl at cut-rate prices". Inter-community conflict has also arisen as some residents object to the sale of buildings and the resultant eviction of long-term residents.
Cabanyal, Valencia, Spain
This section has been nominated to be checked for its neutrality. Discussion of this nomination can be found on the talk page. (October 2012)
Since the end of the 19th century, Cabanyal–Canyamelar has been a district of Valencia, the neighborhood by the sea in Valencia City (Spain). It still retains a gridded urban system because of the "barracas", old typical buildings from Valencia.
Again we see the eternal confrontation: between heritage conservation and "speculative development" of a city. Since the last century, the people of Cabanyal have lived with the threat of the expansion of Blasco Ibáñez Avenue. With the construction of the railway station in Serrería Avenue, we felt that history of this avenue ended. It was the desired connection of Valencia with Sea Villages.
On July 24, 1998, in the congress of Valencia Council, the Popular Party, with its majority, approved the draft of extending Blasco Ibáñez Av. to the sea. The project involves the destruction of 1,651 homes and destruction of urban grid of Cabanyal–Canyamelar, a neighborhood declared Property with Cultural Interest. This project splits the former village into two halves completely isolated from each other.
The project of extending Blasco Ibáñez Avenue to the sea destroys a historic set of ancient buildings. Furthermore, the project also destroys a way of life, of social and human relationships, a culture of special character because of its relationship with the sea.
Since then the neighbors of Cabanyal–Canyamelar–Cap de França have not stopped fighting for their rights and homes, requesting a Plan of Conservation and Rehabilitation of the district without any response by the municipality of Valencia, which has not even agreed to meet the representatives from the neighborhood.
The citizen platform Salvem el Cabanyal tries to stop this gentrification process.

Health Effects of Gentrification
Gentrification is often defined as the transformation of neighborhoods from low value to high value. This change has the potential to cause displacement of long-time residents and businesses. Displacement happens when long-time or original neighborhood residents move from a gentrified area because of higher rents, mortgages, and property taxes.
Gentrification is a housing, economic, and health issue that affects a community’s history and culture and reduces social capital. It often shifts a neighborhood’s characteristics (e.g., racial/ethnic composition and household income) by adding new stores and resources in previously run-down neighborhoods.
Causes of Gentrification
The causes of gentrification are debatable. Some literature suggests that it is caused by social and cultural factors such as family structure, rapid job growth, lack of housing, traffic congestion, and public-sector policies (Kennedy, 2001). Gentrification can occur on a small or large scale. For example, individual newcomers can slowly populate an area because of renovations. Conversely, large-scale redevelopment and the accompanying regeneration can cause an immediate shift in neighborhood residents.
Where people live, work, and play has an impact on their health. Several factors create disparities in a community’s health. Examples include socioeconomic status, land use/the built environment, race/ethnicity, and environmental injustice. In addition, displacement has many health implications that contribute to disparities among special populations, including the poor, women, children, the elderly, and members of racial/ethnic minority groups.
These special populations are at increased risk for the negative consequences of gentrification. Studies indicate that vulnerable populations typically have shorter life expectancy; higher cancer rates; more birth defects; greater infant mortality; and higher incidence of asthma, diabetes, and cardiovascular disease. In addition, increasing evidence shows that these populations have an unequal share of residential exposure to hazardous substances such as lead paint.
Other health effects include limited access to or availability of the following:
•affordable healthy housing
•healthy food choices
•bicycle and walking paths, exercise facilities, etc.
Changes can also occur in:
•violence and crime
•social and environmental justice
This section presents five action steps to minimize the adverse effects of gentrification. Communities can work toward these with the help of planners and public health professionals.
1.Create affordable housing for all incomes •Develop mixed-income communities ◦Mixed-income communities offer a variety of housing prices that could include both single and multifamily units, which provide housing choices for multiple income levels
◦Smart Growth Principles support creating a range of housing opportunities and choices: http://www.smartgrowth.org/about/pri...les.asp?prin=3
◦A Quality Growth Toolkit developed by the Atlanta Regional Commission is a useful tool for implementing mixed– income housing strategies: http://www.atlantaregional.com/html/387.aspx
•Adopt inclusionary zoning policies ◦Inclusionary zoning is a promising policy strategy that allocates a percentage of the rental or for-sale units in housing developments for low- and moderate-income residents. In return, developers receive cost offsets as compensation for their affordable housing contributions: http://www.policylink.org/Projects/IZ/
•Identify incentives (e.g., tax breaks and credits) for planners, developers, and local governments to control displacement ◦For example, see the Brownfield Tax Incentives: http://www.epa.gov/brownfields/html-doc/taxfs_2.htm
2.Approve policies to ensure continued affordability of housing units and the ability of residents to remain in their homes •Consider code enforcement policies that assist residents with home improvements
•Consider implementing rent controls
•Preserve federally subsidized housing programs
•Consider location-efficient mortgages that provide competitive rates and low down payments to those who want to live in “location-efficient communities” that are convenient to resources and reduce the need to drive ◦http://www.locationefficiency.com/
3.Increase individuals’ assets to reduce dependence on subsidized housing •Consider homeownership programs
•Explore job creation strategies and programs
4.Ensure that new housing-related investments benefit current residents •Review development proposals to determine whether the changes could cause displacement ◦For example, conduct a health impact assessment: http://www.cdc.gov/healthyplaces/hia.htm
5.Involve the community •Allow the community to provide input into the design and redevelopment of their neighborhoods
•Educate the community on their available options
•Create organized bodies and partnerships that develop programs to mitigate gentrification

Peanut butter is a food paste made primarily from ground dry roasted peanuts, popular in North America, Netherlands, United Kingdom, and parts of Asia, particularly the Philippines and Indonesia. It is mainly used as a sandwich spread, sometimes in combination with other spreads such as in the peanut butter and jelly sandwich. The United States and China are leading exporters of peanut butter. Other nuts are used as the basis for similar nut butters.

Peanuts are native to the tropics of the Americas and were mashed to become a pasty substance by the Aztec Native Americans hundreds of years ago. A number of peanut paste products have been used over the centuries, and the distinction between peanut paste and peanut butter is not always clear in ordinary use. Early forms of peanut butter, like the Aztecs' version, were nothing but a paste made from roasted peanuts. Modern processing machines allow for very smooth products to be made, which often include vegetable oils to aid in its spreadability.
Evidence of peanut butter as it is known today comes from U.S. Patent 306,727, issued in 1884 to Marcellus Gilmore Edson of Montreal, Quebec, Canada, for the finished product of the process of milling roasted peanuts between heated surfaces until the peanuts entered "a fluid or semi-fluid state." As the peanut product cooled, it set into what Edson explained as being "a consistency like that of butter, lard, or ointment". Edson's patent is based on the preparation of a peanut paste as an intermediate to the production the modern product we know as peanut butter; it does show the initial steps necessary for the production of peanut butter. George Washington Carver is often falsely credited with inventing peanut butter and is nearly synonymous with its history in the United States.
Dr. John Harvey Kellogg patented a "Process of Preparing Nut Meal" in 1895 and used peanuts. Kellogg served the patients at his Battle Creek Sanitarium peanut butter.
Dr. Ambrose Straub, a physician in St. Louis, Missouri, pursued a method for providing toothless elderly with protein in the 1890s. His peanut-butter-making machine was patented in 1903.
January 24 is National Peanut Butter Day in the United States.

Peanut butter has a high level of monounsaturated fats and resveratrol. Peanut butter (and peanuts) provides protein, vitamins B3 and E, magnesium, folate, dietary fiber, arginine, and high levels of the antioxidant p-coumaric acid.
For people with a peanut allergy, peanut butter can cause reactions, including anaphylactic shock, which has led to its being banned in some schools.
Peanut butter is a source of incomplete protein. A common combination to provide a complete protein is pairing peanut butter with whole wheat bread, however, the two foods need only be consumed within 24 hours of each other to complete the protein.
The peanut plant is susceptible to the mold Aspergillus flavus which produces a carcinogenic substance called aflatoxin. Since it is impossible to completely remove every instance of aflatoxins, contamination of peanuts and peanut butter is monitored in many countries to ensure safe levels of this carcinogen. In 1990, a study showed that average American peanut butter contained an average of 5.7 parts per billion of aflatoxins, per the U.S. Food and Drug Administration guidelines of 20 parts per billion.
Some brands of peanut butter may contain a small amount of added partially hydrogenated vegetable oils, which are high in trans fatty acids that are thought to be a cause of atherosclerosis, coronary heart disease, and stroke; these oils are added to prevent the peanut oil from separating from the ground peanuts. Peanuts and natural peanut butter, i.e., ground, dry roasted peanuts without added oils, do not contain partially hydrogenated oils or trans fats. A U.S. Agricultural Research Service (ARS) survey of commercial peanut butters in the U.S. showed that trans fats were undetectable, i.e., below the detection limit of 0.01% of the sample weight. Some commercial peanut butters being advertised as "natural" have supplanted added partially or fully hydrogenated vegetable oils with palm oil, which provides the same benefit of emulsion. However, a 2006 study supported by the National Institutes of Health and the USDA Agricultural Research Service concluded that palm oil is not a safe substitute for partially hydrogenated fats (trans fats) in the food industry, because palm oil results in adverse changes in the blood concentrations of LDL cholesterol and apolipoprotein B just as trans fat does. A 2011 analysis of 23 countries showed that for each kilogram of palm oil added to the diet annually, there was an increase in ischemic heart disease deaths. The increase was much smaller in high-income countries.
A 1974 study found that peanut oil caused relatively heavy clogging of arteries in Rhesus monkeys. Robert Wissler of the University of Chicago reported that diets high in peanut oil combined with cholesterol intake clogged the arteries of Rhesus monkeys more than butterfat. However, subsequent work has cast serious doubt on those findings. Wissler's monkeys were being fed 20 times higher than normal dietary quantities of cholesterol in addition to peanut oil. When a similar 1988 study was performed without abnormal doses of cholesterol, no artery-clogging effect was seen. In fact, peanut oil has been found to lower LDL (bad) cholesterol without reducing HDL (good) cholesterol.
Peanut butter can harbor Salmonella and cause salmonellosis, as in the Salmonella outbreak in the United States in 2007. In 2009, due to mishandling and apparent criminal negligence at a single Peanut Corporation of America factory in Blakely, Georgia, Salmonella was found in 46 states in peanut-butter-based products such as crackers, peanut-butter cookies, and dog treats. It had claimed at least nine human lives as of 17 March 2009 and made at least 691 people sick in the United States.
Peanut butter cookies, a popular type of cookie made from peanut butter and other ingredients.
Peanut butter is included as an ingredient in many recipes, especially cookies and candies. Its flavor combines well with other flavors, such as chocolate, oatmeal, cheese, cured meats, savory sauces, and various types of breads and crackers.
In addition to jelly, in a peanut butter and jelly sandwich, peanut butter is said by some to combine well with pickles, mayonnaise, olives, onion, horseradish, bacon, Marmite, or Vegemite in a sandwich. Elvis is said to have liked sandwiches made with peanut butter, banana and bacon while Hemingway is said to have liked thick onion slices in a peanut butter sandwich.
A flavorful, appealing snack for children is called "Ants on a Log"; a celery stick is the "log", and raisins arranged in a row along a base of peanut butter are the "ants".
Plumpy'nut is a peanut butter-based food used to fight malnutrition in famine stricken countries. A single pack contains 500 calories, can be stored unrefrigerated for 2 years, and requires no cooking or preparation.
By placing a medium amount of peanut butter inside the opening of a hollow sturdy chew toy, it is easy to create a toy that will keep a dog occupied for as long as an hour. Most dogs enjoy the challenge of reaching the peanut butter with their tongue and extracting it.
A common, simple outdoor bird feeder can be made by coating a pine cone once with peanut butter, then again with birdseed.
The oils found in peanut butter are known to allow chewing gum to be removed from hair.
A slang term for peanut butter in World War II was "monkey butter".
In Dutch peanut butter is called pindakaas (peanut cheese), because the name butter was protected in the Netherlands when peanut butter came on the market in 1948. The word kaas, cheese, was already being used in another product (leverkaas, Leberkäse) that has no cheese in it.
In the 1960s, collectible glasses related to characters from the Oz Books were sold as promotions with "Oz, the Wonderful Peanut Spread." The product was forced to rename itself a peanut butter when the USDA informed the company that, under food laws, a "peanut spread" has a lower peanut percentage than a "peanut butter."
