The net effect of the many changes from the 1880 census (the larger population, the number of data items to be collected, the Census Bureau headcount, the volume of scheduled publications, and the use of Hollerith's electromechanical tabulators) was to reduce the time required to fully process the census from eight years for the [[U.S. Census, 1880|1880 census]] to six years for the 1890 census.<ref name="11th census report">{{cite book |title=Report of the Commissioner of Labor In Charge of The Eleventh Census to the Secretary of the Interior for the Fiscal Year Ending June 30, 1895 |url=http://hdl.handle.net/2027/osu.32435067619882 |___location=Washington, DC ||publisher=[[United States Government Publishing Office]] |date=July 29, 1895 |accessdate=November 13, 2015 |oclc=867910652}} Page 9: "You may confidently look for the rapid reduction of the force of this office after the 1st of October, and the entire cessation of clerical work during the present calendar year. ...

This census is also notable for the fact it is one of only three for which the original data is no longer available. Almost all the population schedules were destroyed following a fire in 1921.
