The 1940 United States Census was the sixteenth national census conducted in the United States, taking place on April 1, 1940. It aimed to gather demographic information about the population, including age, sex, race, and marital status. This census was significant as it was the first to include questions about income and education, reflecting the economic challenges of the time. The results of the 1940 Census showed a population of approximately 132 million people, marking a 7.3% increase since the previous census in 1930. The data collected provided valuable insights for government planning and resource allocation during the Great Depression and World War II.
