The Fourteenth United States Census, conducted by the Census Bureau 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.
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.
