1950 United States Census was the seventeenth decennial enumeration of the United States population, conducted by the Census Bureau on April 1, 1950. It recorded a resident population of 150,697,361, a significant increase from the 1940 United States Census. The census was notable for its expanded scope, technological innovations in data processing, and its documentation of the profound demographic shifts following World War II and the onset of the Cold War.

Background and legislation

The authorization for the 1950 census stemmed from Article I, Section 2 of the United States Constitution, which mandates an enumeration every ten years. The specific procedures were governed by the Census Act of 1929, which established the permanent framework for decennial counts. The post-World War II environment presented unique challenges, including tracking the massive internal migration of the Great Migration and the early effects of the G.I. Bill. Planning was overseen by Census Bureau directors like J. C. Capt and Robert W. Burgess, who navigated the increased demands for statistical data from federal agencies such as the Department of Defense and the Department of Commerce.

Data collection and methodology

For the first time, the Census Bureau employed a UNIVAC I (Universal Automatic Computer) to process a substantial portion of the data, marking a revolutionary shift from punched-card tabulators to electronic computing. Enumerators visited households to collect information using a detailed questionnaire that included new inquiries about residential plumbing and kitchen facilities. The bureau also introduced advanced sampling techniques for the long-form questionnaire, sent to a 20% sample of the population, to gather more detailed socioeconomic data without overburdening every household. Field operations were managed from regional offices across the country, including major hubs in New York City, Chicago, and Los Angeles.

Population findings

The census confirmed the United States' continued growth, with the national population surpassing 150 million. The geographic center of population moved further west to Richland County, Illinois, near the town of Olney, reflecting the ongoing shift toward the Sun Belt. California solidified its explosive growth, overtaking Pennsylvania to become the second most populous state behind New York. The data quantified the dramatic expansion of suburbs, such as those around Levittown, New York, fueled by veterans utilizing the G.I. Bill. Furthermore, it recorded the beginnings of the Baby Boom, providing a crucial baseline for this demographic phenomenon.

Data availability and release

Under the "72-Year Rule," the original census records, containing individual names and responses, were scheduled for public release by the National Archives and Records Administration in April 2022. Prior to this, only statistical summaries were available. The 1950 census was the first to have its individual records digitized and made searchable online at launch through a partnership between the National Archives and leading genealogy websites like Ancestry.com and FamilySearch. This massive digitization project involved processing millions of pages of enumeration district maps and microfilmed population schedules.

Impact and legacy

The data from this census was instrumental in the postwar reorganization of the United States Congress, leading to the reapportionment of House seats and the redrawing of congressional districts. It provided critical evidence for landmark civil rights cases, such as those argued by the NAACP Legal Defense Fund, by documenting patterns of racial segregation and inequality. The socioeconomic information gathered informed major federal policy initiatives, including the Interstate Highway System and housing programs under the Housing and Home Finance Agency. Demographically, it serves as an essential snapshot of American society at the dawn of the Cold War, the civil rights era, and the peak of the Baby Boom.
