About U.S. Enumeration District Maps and Descriptions, 1940

Get a bird’s-eye view of your ancestor’s neighborhood in the 1940 United States Federal Census with enumeration district maps.

The 1940 census was split into enumeration districts—geographic areas designed to allow a census taker (enumerator) to visit every house in the district within a two-week period (in rural areas, the time allowed was one month). Enumeration district maps illustrate these districts’ boundaries.

Also included in this collection are descriptions of the district boundaries. Maps and descriptions can be particularly helpful when using a version of the 1940 census that has not been indexed (not searchable by a person’s name).

Enumeration district boundaries have changed over the years. So it is entirely plausible that even if an ancestor appears in the same enumeration district in consecutive censuses, he or she may be in a different district for 1940.

These maps and descriptions are meant to be used in conjunction with the 1940 United States Federal Census. Street names can be searched in the keyword field if the street name is included in the ED description.
