The Indiana 1940 census images are now available for indexing with FamilySearch! You can join the Indiana Genealogical Society in helping to index these records as part of the 1940 U.S. Census Community Project (http://the1940census.com).
Start by watching the 1940 Census Indexing Training videos (https://the1940census.com/video-training/). There you will learn how to download the FamilySearch Indexing software, create a FamilySearch account, index the 1940 census and associate yourself with a society.
Make sure to associate your FamilySearch account with the Indiana Genealogical Society. This will make both you and our society eligible for prizes (https://the1940census.com/blog/games-prizes/). IGS receives credit for all 1940 census indexing, not just the Indiana census pages. So feel free to index states where your ancestors lived or to to index a batch from each state.
You can keep up to date on the progress of the 1940 U.S. Census Community Project at https://www.familysearch.org/1940census/ - the site has a map where you can hover your mouse over a particular state and see the percentage of records that have been indexed.
If you have any questions about how to help the Indiana Genealogical Society in indexing the 1940 census, please contact IGS Vice President Tina Lyons at email@example.com.
