Atlas of Historical County Boundaries

Data Detectives Ed and Michael have noted the Atlas of Historical County Boundaries, which "is meant to be a resource for people seeking records of past events, and people trying to analyze, interpret and display county-based historical data like returns of elections and censuses, and for people working on state and local history projects. The special interests of those potential users range from history to demography, economics, genealogy, geography, law, and politics."

The page features interactive maps of every county, extinct county, and unsuccessful county proposal from the creation of the first county through 31 December 2000; plus an index of counties and equivalents, with individual and statewide county chronologies. See how county boundaries changed over time.
