The 1900 United States Census was the twelfth national census conducted in the United States, taking place on June 1, 1900. It aimed to count the population and gather demographic information, including age, sex, race, and occupation. This census recorded approximately 76 million people, reflecting the country's growth and changes since the previous census in 1890. The 1900 census was notable for introducing new questions about the number of years individuals had been married and the number of children born to women. The data collected helped inform government policies and social programs, contributing to a better understanding of the American population at the turn of the century.
