Racial Enclaves and Density Zoning: The Institutionalized Segregation of Racial Minorities in the United States

Abstract

Previous research on segregation stresses things like urban form and racial preferences as primary causes. The author finds that an institutional force is more important: local land regulation. Using two datasets of land regulations for the largest U.S. metropolitan areas, the results indicate that anti-density regulations are responsible for large portions of the levels and changes in segregation from 1990 to 2000. A hypothetical switch in zoning regimes from the most exclusionary to the most liberal would reduce the equilibrium gap between the most and least segregated Metropolitan Statistical Areas by at least 35% for the ordinary least squares estimates.
