Douglas S. Massey, PhD is the Henry G. Bryant Professor of Sociology and Public Affairs
at the Woodrow Wilson School of Public and International Affairs at Princeton University. Dr. Massey examines the sociology of immigration especially the consequences of residential segregation for African Americans and Latinos of African ancestry in the United States. He has shown that segregation figures prominently in black underachievement that interacts with shifts in the U.S. income distribution to yield a rising concentration of poverty. That poverty intensifies social disorder and violence undermining the health of African Americans reducing their life expectancy and impairing cognitive development.
