The 1890 United States Census was the eleventh national census conducted in the United States. It aimed to count the population and gather demographic information, including age, sex, race, and occupation. This census was notable for being the first to use a machine, developed by Herman Hollerith, to process data, which significantly sped up the counting process. However, the results of the 1890 Census were largely lost due to a fire in 1921, which destroyed many records. Despite this setback, the census provided valuable insights into the growing population and changing demographics of the United States during that period.
