Diagram of U.S. Census Changes from 1790 to 1940
Here's an infographic to show you the states or territories included in each U.S. Federal census, 1790–1940. Knowing these facts can save you from trying to find your ancestor in a state that didn't yet exist.
After the first census box for 1790, each year in the infographic shows:
- The new states and territories counted that year.
- New questions asked and facts recorded that year.
It's interesting to see the increasing detail gathered from census to census. In another article I'll explain some of the history that led to adding those particular questions to the census.
You can download this graphic as a PDF. I've also created a printer-friendly version in black and white for letter-size paper (8½" x 11").
