- For the United States
- For 1980 to 1990 and vice versa, try MABLE '98/Geocorr v3.0 Geographic Correspondence Engine. It is an interactive site that generates "correlation lists" between two geographic areas. On the list of areas are 1980 counties, 1990 counties, and 5-digit Postal Zip Code (circa 1991).
- For 2000 geographic areas, see MABLE/Geocorr2K: Geographic Correspondence Engine with Census 2000 Geography
- For the latest geography, see MABLE/Geocorr2014.
- Also see US2010. US2010 presents a Longitudinal Tract Data Base (LTDB), which provides public-use tools to create estimates within 2010 tract boundaries for any tract-level data (from the census or other sources) that are available for prior years as early as 1970.
- For geographies including school districts and state and legislative districts, use the Census site.
- For assistance with boundary files, contact the GIS service in Lewis Library.
- Also see the Archive of Census Related Projects.
- United States Congressional District Shapefiles provides digital boundary definitions for every U.S. congressional district in use between 1789 and 2012.
- Matching 2010 Census geography to 2000 Census geography.
- Congressional district shape files back to 1789.
- For Canada
- Use the Census Boundary Files from Statistics Canada (1996+)
