The Eleventh United States Census was taken June 2, 1890. The total population was found to be 62,947,714. Most of the 1890 census materials were destroyed in a 1921 fire.
The data was tabulated by machine for the first time. Herman Hollerith invented this way of tabulating data. This technology made the time to tabulate the census change from eight years for the 1880 census to one year for the 1890 census.
