Hollerith's machines processed the 1890 census returns, reducing processing time from eight years to six years.
The Census Office used Hollerith's tabulators under contract for the 1890 census. The 1890 Tabulator was hardwired to operate on 1890 Census cards. This adoption reduced the time required to process the census from eight years for the 1880 census to six years for the 1890 census.
