Source
The segregation dataset found at this site was created by David Cutler, Edward Glaeser, and Jacob Vigdor. The data come from decadal Census data spanning the years 1890 to 1990. These data have been used in Cutler and Glaeser's Are Ghettos Good or Bad? (1997: Quarterly Journal of Economics 112:827-872) and Cutler, Glaeser and Vigdor's The Rise and Decline of the American Ghetto (1999: Journal of Political Economy 107:455-506).
In addition to the segregation data, supplemental city/metropolitan area data and the original ward and tract data used to construct the indices can be found below.
Users of the historical segregation data should cite The Rise and Decline of the American Ghetto. Users of the 1990 supplemental data should cite Are Ghettos Good or Bad?
