NARA released the 1950 population census schedules for researcher use on April 1, 2022, at  This is the 56th in a series of blog posts on the 1950 census. 

What if the 1950 census says "No one at home - See Sheet 72 lines 21-23" but there are only 20 pages census records for the Enumeration District (ED).  Is the page lost?  NO !  Do not assume that the pages are numbered from 1 to 20!  Go to the last image in that ED.  Look at the census page.  Look for the "Sheet Number" in the upper right corner, then go back a page or two or more until you see the sheet number you want!

Examples of "No One at Home" Entries

Most census enumerators needed fewer than 40 pages for the Enumeration District because the optimal size for an ED was 900 to 1,200 persons.  Since there are 30 lines per page on the standard Form P1, 1950 Census of Population and Housing, that means most standard ED's will have about 40 pages or less (1,200 people divided by 30 equals 40 pages). 

The Census Bureau planned the "call back" procedure in advance, and they wanted it done a standard way ... so ... no matter how few pages the enumerator needed, he or she was to put all call backs on sheets numbered 71 or higher.  Read 1950 Census:  Enumerated Out-of-Order - "Callbacks" and Others on Page 71 and Up.  You'll find the sheet number in the upper right corner - see below.

Where is Sheet 71 if there are only 18 pages for my ED?  Just because there are 18 pages (images) that doesn't mean the pages are numbered from 1 to 18!  Let's look at Los Angeles County, California, ED 19-1.  There are 18 pages (images) but Sheet 71 is the 16th page (image) followed by Sheet  72, then Sheet 73!
