The 1920 United States census, conducted by the Census Bureau during one month from January 5, 1920, determined the resident population of the United States to be 106,021,537, an increase of 15.0 percent over the 92,228,496 persons enumerated during the 1910 census.

The 1920 Census was determined for 1 January 1920. The actual date of the enumeration appears on the heading of each page of the census schedule, but all responses were to reflect the individual's status as of 1 January, even if the status had changed between 1 January and the day of enumeration.

Despite the constitutional requirement that House seats be reapportioned to the states respective of their population every ten years according to the census, members of Congress failed to agree on a reapportionment plan following this census, and the distribution of seats from the 1910 census remained in effect until 1933. In 1929, Congress passed the Reapportionment Act of 1929 which provided for a permanent method of reapportionment and fixed the number of representatives at 435.

This was the first census in which the United States recorded a population of more than 100 million. It was also the first census in which a state—New York—recorded a population of more than ten million.

This census also marked a significant population shift from rural to urban. According to the Census Bureau, "Beginning in 1910, the minimum population threshold to be categorized as an urban place was set at 2,500. "Urban" was defined as including all territory, persons, and housing units within an incorporated area that met the population threshold. The 1920 census marked the first time in which over 50 percent of the U.S. population was defined as "urban."^[1]

Data availability

The original census enumeration sheets were microfilmed by the Census Bureau in the 1940s, after which the original sheets were destroyed.^[5] The microfilmed census is available in rolls from the National Archives and Records Administration. Several organizations also host images of the microfilmed census online, and digital indices.

Microdata from the 1920 census are freely available through the Integrated Public Use Microdata Series. Aggregate data for small areas, together with electronic boundary files, can be downloaded from the National Historical Geographic Information System.
