Finding historic census data can be a little difficult. The Census Bureau makes available the data from the 2010 and 2000 Censuses online at American Factfinder. However, they do not provide access to the earlier censuses any longer.
This is the new interface for census data. At this time, only the 2010 & 2000 censuses are available. Check "Datasets" under "Topics" to see what other data is available. The original American Factfinder still has relevant data, but will eventually go away.
The National Historical Geographic Information System (NHGIS) is a project to create and freely disseminate a database incorporating all available aggregate census information for the United States between 1790 and 2000. STILL UNDER CONSTRUCTION!
*Collect and enrich historical and contemporary U.S. Census summary data.
* Incorporate these data into a Geographic Information Systems framework.
*Create a web-based system for access to both census data and the metadata.
This resource lets you visualize historical and current census data. Social Explorer also includes data for crime, health, religion, censuses for Canada and the United Kingdom and development indicators.
This guide comes from the University of Michigan's Library. Most of the resources it points to are freely available. There may be some that are limited to Michigan's students, staff and faculty. If that happens, check with our own online catalog, the Baker/Berry Reference Desk or the Evans Map Room for alternatives.
