How to Locate an Enumeration District
To identify an individual's enumeration district, you’ll need to know where they were living at the time the census was taken, including the state, city and street name. The street number is also very helpful in larger cities. With this information, the following tools can help you locate the Enumeration District for each census:
- Stephen P. Morse’s One-Step Tools website includes ED Finder tools for the 1880, 1900, 1910, 1920, 1930, and 1940 U.S. federal censuses.
- Morse’s One-Step site also offers an ED conversion tool for converting between 1920 and 1930, and 1930 and 1940 Censuses.
- The National Archives has online ED maps and geographic descriptions for the 1940 census.
