The 1940 Census was the 16th national census conducted in the United States, taking place on April 1, 1940. It aimed to collect 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 Great Depression. The results of the 1940 Census provided valuable insights into the American population during a time of change. The data helped inform government policies and programs, especially as the nation prepared for involvement in World War II. The census records are now a vital resource for historians and genealogists.
