Evolution of Racial and Ethnic Segregation: Pace and Place of Neighborhood Change (2010)

Michael D. M. Bader Presented at the University of Pennsylvania Sociology Colloquium, Philadelphia, Pennsylvania.


Sociological research identifies racial segregation as a primary factor that perpetuates racial inequality. The continued influence of racial segregation depends on the patterns of neighborhood racial and ethnic change that evolve in the present multicultural, post-Civil Rights era. I argue that exploring the pace of neighborhood change and the places where change occurs links individual-level processes to metropolitan level changes in racial and ethnic segregation. To study the pace and place of emerging types of neighborhood change, I present novel graphical and statistical methods --~ternary plots and growth mixture models~-- that allow me to reduce the complexity of measuring continuous levels of long-term change in composition among multiple groups. Using the Chicago metropolitan area as a case-study, I show that the pace of neighborhood change slows considerably after the 1970s and that contemporary patterns of neighborhood change evolve over multiple decades with specific spatial patterns. Uncovering the location of change in time and space explains the evolution of racial and ethnic segregation through black diffusion from traditionally black neighborhoods, Latino dispersion to new suburban enclaves, and white divergence into gentrifying areas and the distant suburbs.
