Social Explorer
Created by Queens College, City University of New York, and partnering with the University of Minnesota's own National Historical Geographic Information System, this subscription edition of Social Explorer offers the ability to create customized maps and reports of demographic, housing, and employment patterns throughout the United States using data from the U.S. Census Bureau. Data are available by decade between 1940 and 2000 for a variety of geographical entities that are as small as the census tract for certain areas.
