The 1950 Census – A Research Guide

by Kimberly Powell | 1 Apr 2022

Census Day: 1 April 1950
Time to Complete: About two months
U.S. Population: 150.7 million

On April 1, 1950, 140,000 census enumerators began conducting the 17th decennial census of the United States. All responses were to reflect the individual’s status as of 1 April 1950, even if their situation changed between 1 April and the day the census taker visited (e.g., children born after 1 April should not be listed, and people who died after 1 April should be counted). The 1950 census covered the continental United States, the territories of Alaska and Hawaii, American Samoa, the Canal Zone, Guam, Puerto Rico, the Virgin Islands of the United States, and some of the smaller island territories.

The format used in the 1950 census was similar to 1940, but with fewer questions asked of most individuals. Additional questions were asked of six persons whose name fell on a highlighted line labeled “Sample”; the sixth person was also asked additional questions. Special forms were used to collect information from the large number of military and government workers living overseas with their families. College and university students were enumerated at their college residences where they normally lived rather than at home with their parents. Native Americans residing on reservations were recorded on the original schedule, but a supplemental schedule was used to obtain additional information including other name(s) by which that person was known, their tribe, clan, degree of Indian blood, ability to read, write, or speak English or any other language, and participation in any native Indian ceremonies in 1949. These schedules are available online in addition to the population schedules.
