The 1950 U. S. Census is scheduled for public release on April 1, 2022.
Until an every-name index is available (underway at FamilySearch.org), researchers will have to browse census returns by Enumeration District.
To prepare for your success, we suggest the following resources.
1950 Census Articles posted at the History Hub Blog (National Archives) — click here to browse the list
Enumerator’s Reference Manual — click here to read or download free from Google Books
Tennessee County Enumeration District Maps — click here to select from the list provided by TGS
These maps were drawn on 1939 State Highway Department maps, which are themselves worthwhile to researchers.
