In 2022, the 1950 census will be released. It will be several months before all the names will be indexed by the big databases. When the 1940 census was released in 2012, I remember the frustration of not being able to figure out just where on the census my family could be found. I have just found some maps that may help when the time comes:
The National Archives has digitized Enumeration maps for the 1940 and 1950 census on their website. If you know roughly where your family lived during the census, you can narrow your search! This will help until the name index comes out. I have linked to the Ouachita Parish maps, but they have several other places available. Keep this in the back of your mind until 2022! It just may save you some frustration!
