The Metropolitan Planning Council, together with Urban Institute and a team of regional policy advisors, analyzed segregation patterns in the 100 largest metropolitan areas in the country. They examined three types of segregation: economic segregation, African American white segregation and Latino-white segregation. They then examined what impacts we would see if the Chicago region reduced its levels of segregation to the median levels of segregation of the nation’s 100 biggest metros. The core of this report is a summary of their findings. The findings for African American-white segregation were the most pronounced in our study, yet they are not the only indicator of how segregation is experienced by race in this region. Additional data about the impact of segregation on Latinos at other points in this report are shared.
