Converting between Census EDs in One Step

The 1940 US Census will not become public until April 2, 2012. This utility will help you determine the 1940 Enumeration District (ED) in advance of the 2012 date, so you will be ready to access the census sheets and not have to wait for a name index.

For most small cities, the 1940 ED numbers (as well as the 1930 ED numbers) can be found directly with this utility. In that case, after you select the state you would select the city, and a set of ED numbers for that city will be displayed. If it really is a small city, there won't be many EDs and you can easily search through each one looking for the address that you want.

For larger cities, this utility will let you obtain the 1940 ED number of an address if you already know the ED number of that address in the 1930 census. The 1930 ED number can be obtained using the One-Step tool at http://stevemorse.org/census. Once you obtain the 1930 ED number with that tool, you will be presented with a button that links you back to this utility to do the conversion.

An alternate approach for large cities is to use the One-Step tool at http://stevemorse.org/census/index.html?year=1940 and obtain the 1940 ED number directly from the address (no need to know the 1930 ED number).

For all other areas, you would again use this utility to convert the 1930 ED number to the 1940 one, but in this case you would get the 1930 ED number from either the One-Step tool at http://stevemorse.org/census/ed1930.html or the National Archives website at http://1930census.archives.gov
