The creation of highways separated and, in some cases, isolated black neighborhoods from goods and services, often in industrial corridors. For example, Birmingham`s Interstate Highway System sought to maintain the racial boundaries established by the city`s Racial Zone Act of 1926. The construction of highways through the city`s black neighborhoods has resulted in a significant loss of population in these neighborhoods and is associated with an increase in racial segregation in the neighborhood. [85] Table 2 examines the process of suburbanization and segregation for Blacks by estimating the three-equation model given above. The left columns show an equation that predicts the relative suburbanization of blacks, which carries an R2 of only 0.307 and has no significant effect on the characteristics of blacks themselves, suggesting that they are generally unable to translate socioeconomic achievements into suburban residences. Instead, the relative suburbanization of blacks is entirely determined by a handful of metropolitan characteristics, including the percentage of foreign-born individuals, the median year of house construction, the restriction of suburban density, the percentage of homeowners, the degree of anti-black sentiment, the size of the urban population, and the percentage of suburbs in 1970, with the protocol of the military population to p marginally significant. <0.10 The profile of a relatively suburbanized Black population is that of a small MSA in which the overall level of suburbanization had increased by 1970 and which had a relatively large immigrant population, a newer housing stock, a less restrictive suburban density regime, a large proportion of homeowners and a large military population – all expected effects. The only surprise is that black suburbanization is positively predicted by higher levels of anti-black sentiment, which could suggest that authorities in racially biased metropolitan areas were more aggressive in the 1990s and 2000s to demolish public housing projects and thus displace poor African Americans to the inner suburbs. The middle equation in Table 2 examines how the relative suburbanization of blacks affects metropolitan black segregation, which controls other independent variables. As you can see, any single increase in relative suburbanization reduces black and white dissimilarity by three points. Although the socioeconomic status of blacks did not predict a relative suburbanization of blacks, it does have a strong effect on predicting the overall level of segregation of blacks. The model suggests that any increase in the relative income of blacks is associated with a 15.5-point decrease in black segregation, and that any increase in the relative education ratio of blacks is associated with a 13.0-point decrease in segregation. As a result, transferring income and education from their observed minima to maxima would reduce the segregation of black residential areas by 15.0 and 24.9 percentage points, respectively.

Uniformity is the difference between the percentage of a minority group in a given part of a city relative to the city as a whole. Exposure is the probability that a minority and a majority party will come into contact with each other. Grouping consists of bringing together different minority groups in a single space; Regroupment often leads to a large ghetto and the formation of hyper-ghettoization. Centralization measures the tendency of members of a minority group to be in the middle of an urban area, often calculated as a percentage of a minority group living in the middle of a city (as opposed to peripheral areas). Concentration is the dimension that refers to the actual amount of land on which a minority lives in their respective cities. The higher the segregation in that particular area, the smaller the amount of land that a minority group will control. Historically, residential segregation has divided communities between the black downtown and white suburbs. This phenomenon is due to the flight of whites, in which whites often actively leave the neighborhood due to a black presence. There are not only geographical consequences as money goes and poverty increases, crime rates rise, and businesses leave the money and follow the money. This leads to job shortages in segregated neighborhoods and perpetuates economic inequality in the city center.
