How do I search 1950 U.S. Census records with an address?

At https://1950census.archives.gov, look at the Enumeration District maps provided with the county to help narrow your search. In most counties, if you click on the "ED Maps" icon for any enumeration district you will then be able to see the maps for the entire county - https://historyhub.history.gov/servlet/JiveServlet/downloadImage/2-45530-732328/pastedImage_1.png

In addition to our 1950 census website, searchable written descriptions of a county's enumeration districts can be found at https://stevemorse.org/ed/ed.php and a tool for finding the exact enumeration in large cities can be found at https://stevemorse.org/census/unified.html
