A ghetto is a part of a city in which members of a minority group live, especially as a result of political, social, legal, environmental or economic pressure. Ghettos are often known for being more impoverished than other areas of the city. Versions of such restricted areas have been found across the world, each with their own names, classifications, and groupings of people.

Facilities and services such as housing, healthcare, education, employment, and transportation have been systematically separated in the United States on racial categorizations. Segregation was the legally or socially enforced separation of African Americans from whites, as well as the separation of other ethnic minorities from majority and mainstream communities. While mainly referring to the physical separation and provision of separate facilities, it can also refer to other manifestations such as prohibitions against interracial marriage, and the separation of roles within an institution. The United States Armed Forces up until 1948, black units were typically separated from white units but were still led by white officers.

Edward Soja uses the term fractal city to describe the "metropolarities" and the restructured social mosaic of today's urban landscape or "postmetropolis". In his book, Postmetropolis: Critical Studies of Cities and Regions, he discusses how the contemporary American city has become far more complex than the familiar upper class vs. middle class or black vs. white models of society. It has become a fractal city of intensified inequalities and social polarization. The term "fractal" gives it the idea of having a fractured social geometry. This is a patterning of metropolarities, or an intensification of socio-economic inequalities, some of which Soja tries to pinpoint and discuss.
Economic restructuring is used to indicate changes in the constituent parts of an economy in a very general sense. In the western world, it is usually used to refer to the phenomenon of urban areas shifting from a manufacturing to a service sector economic base. It has profound implications for productive capacities and competitiveness of cities and regions. This transformation has affected demographics including income distribution, employment, and social hierarchy; institutional arrangements including the growth of the corporate complex, specialized producer services, capital mobility, informal economy, nonstandard work, and public outlays; as well as geographic spacing including the rise of world cities, spatial mismatch, and metropolitan growth differentials.

Concentrated poverty concerns the spatial distribution of socio-economic deprivation, specifically focusing on the density of poor populations. Within the United States, common usage of the term concentrated poverty is observed in the fields of policy and scholarship referencing areas of "extreme" or "high-poverty." These are defined by the US census as areas where "40 percent of the tract population [lives] below the federal poverty threshold." A large body of literature argues that areas of concentrated poverty place additional burdens on poor families residing within them, burdens beyond what these families' individual circumstances would dictate. Research also indicates that areas of concentrated poverty can have effects beyond the neighborhood in question, affecting surrounding neighborhoods not classified as "high-poverty" and subsequently limiting their overall economic potential and social cohesion. Concentrated poverty is a global phenomenon, with prominent examples world-wide. Despite differing definitions, contributing factors, and overall effects, global concentrated poverty retains its central theme of spatial density. Multiple programs have attempted to ameliorate concentrated poverty and its effects within the United States, with varying degrees of progress and to sometimes detrimental effect.
The definition of mixed-income housing is broad and encompasses many types of dwellings and neighborhoods. Following Brophy and Smith, the following will discuss “non-organic” examples of mixed-income housing, meaning “a deliberate effort to construct and/or own a multifamily development that has the mixing of income groups as a fundamental part of its financial and operating plans” A new, constructed mixed-income housing development includes diverse types of housing units, such as apartments, town homes, and/or single-family homes for people with a range of income levels. Mixed-income housing may include housing that is priced based on the dominant housing market with only a few units priced for lower-income residents, or it may not include any market-rate units and be built exclusively for low- and moderate-income residents. Calculating Area Median Income (AMI) and pricing units at certain percentages of AMI most often determine the income mix of a mixed-income housing development. Mixed-income housing is one of two primary mechanisms to eliminate neighborhoods of concentrated poverty, combat residential segregation, and avoid the building of public housing that offers 100% of its housing units to those living in poverty. Mixed-income housing is built through federal-, state-, and local-level efforts and through a combination of public-private-non-profit partnerships.

The Truly Disadvantaged: The Inner City, the Underclass, and Public Policy is a book by William Julius Wilson. The book was first published in 1987; a second edition was published in 2012. It examines the relationship between race and poverty in the United States, and the history of American inner-city ghettos. The broad-ranging book rejects both conservative and liberal arguments for the social conditions in American inner cities. In it, Wilson argues that the decline of such conditions is due to "basic economic changes which radically altered the occupational structure of the central cities," such as the withdrawal of large industries from inner cities during the 1970s. He also criticizes the architects of the War on Poverty during the 1960s, saying that they focused too much on poverty as a problem of environment rather than as a problem of "economic organization".
