- For the United States
- For 1980 to 1990 and vice versa, try MABLE Geocorr 90 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/Geocorr2000: Geographic Correspondence Engine with Census 2000 Geography
- For the latest geography, see MABLE/Geocorr2018.
- See "Code for merging ZIP code level datasets with the UDS Mapper ZIP code to ZCTA crosswalk".
- 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.
- Congressional district shape files back to 1789.
- Use the FCC Area API to match census geography to latitudes/longitudes.
- For Canada
- Use the Census Boundary Files from Statistics Canada (1996+)
