Primary Sources in African-American History

Census information compiled at the portal describes the racial-ethnic diversity of U.S. states, metropolitan and micropolitan areas, counties, and places (e.g., cities, suburbs, small towns) for the 1980-2010 period. This information can be accessed in three ways. A summary measure of diversity (the entropy index), panethnic group counts and proportions, and simple compositional graphics are available on a case-by-case basis via pull-down menus.

Contains more than 150 interactive maps and thousands of "area descriptions" from Home Owners' Loan Corporation (HOLC). These materials afford an extraordinary view of the contours of wealth and racial inequality in Depression-era American cities and insights into discriminatory policies and practices that so profoundly shaped cities that we feel their legacy to this day.
