The 1900 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, such as age, sex, race, and occupation. This census recorded data for approximately 76 million people, reflecting the country's growth and changes since the previous census in 1890. The 1900 Census was notable for being the first to include 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 in the early 20th century.
