Here’s the latest on genealogy websites where you can find the 1940 census and which states you can search by an ancestor’s name:
Ancestry.com: Record images for all US states and territories are available free, as are searchable name indexes for Delaware, Nevada and Washington, DC. A chart on the 1940 census page lets you see indexing progress.
Archives.com: At this 1940 Census Community Project partner site, you can search name indexes to Colorado and Delaware. To access the unindexed portion of the census, this site sends you to the National Archives’ 1940 census site (which Archives.com designed and hosts).
FamilySearch: Digitized records are available here for all US states and territories.
FamilySearch just announced that more than 85,000 1940 Census Community Project volunteers have already finished indexing 20 percent of the census, and thousands more volunteers sign up every week.
Not all the indexed records are available to search online yet. FamilySearch’s indexing progress map colors searchable states orange; so far, you can search name indexes for the states of Delaware and Colorado. To search, click the state on the map. (I clicked on Kansas and tried a search because Community Project partner FindMyPast.com has a Kansas index, but the results were people in Colorado.)
FindMyPast.com: On this 1940 Census Community Project partner site, digitize records are available for most states. Records for Texas, California, Utah, Tennessee, Minnesota, Wisconsin and several others are missing. You can search name indexes for Delaware, Colorado and Kansasexcept for Kansas, they’re the same states as for FamilySearch, because it’s the same index.
MyHeritage: Records for all states and territories are available now for free. This site introduced the first searchable index, for the state of Rhode Island, but hasn’t added any other states since. MyHeritage also has updated its mobile app so you can search 1940 census records from your iPhone, iPad or Android phone.
The 1940 census record images also are available on FamilyLink.com, which MyHeritage purchased last year. You’ll need to register for a free account on the site (if you don’t already have an account there) to view the records.
National Archives: Records for all states and territories are available here for free.
