The U.S. Census Bureau conducts several data collection programs about the U.S. population which have their own language, geography, and data portals. This guide is based on a similar guide created by Kelly Smith at UCSD.

1950 Census Enumeration Forms

April 1, 2022 is the release date for the 1950 Census records, the original enumeration forms which include names, ages, occupations, household relationships, addresses, and a host of related information about the American people.  1950 was the 17th time in American history that a complete counting of the population was conducted.  Information about this data release is provided by the National Archives 1950 Census Records website.  From this site you can find the Questions Asked on the 1950 Census, census forms used to collection census information, Native Americans in the 1950 Census, and much more information to help you make effective use of this enormous resource.

Enumerations forms, also called surveys or questionnaires, are kept private for 72 years after which the National Archives and the Census Bureau make these records available to the public. 

Total Population 1950:  151,325,798 in 48 states.  This was a 14.5 % increase from the 1940 Census.

  • Number of Enumerators:                   142,962
  • Total Pages in Published Reports:     61,700

Counting all those people to generate statistical tables required customized technology, including UNIVAC I, the first successful civilian computer. Below are a few images of the people who worked, and the technology used, to compile the 1950 Census.

The Census Bureau 1950 Census Records page also provides information about the 1950 Census, how it was conducted, and what you can find using the 1950 Census Records.  Blog Posts on the 1950 Census provide insight into what questions were asked, how enumerators did their work, language barriers experienced by enumerators, how Native Americans were counted, how many people it took to gather and process the data, and much more.

Bulk download of the full dataset, inclusive of metadata index, enumeration district maps, and enumeration district descriptions (>165 Terrabytes, 10x the size of the 1940 Census dataset) will also be available via Amazon Web Services Registry of Open Data for those who wish to explore aggregations of the records or post the information to their own websites.
