Herman Hollerith’s tabulating system sped up the 1890 census, but there was still a lot of manual work involved. Most holes in each of the 60 million cards were individually punched, and the cards were moved and stacked by hand. A similar process was later used by the Department of Agriculture for farm censuses.
