Census and History \| Census and Law \| Census and Math The rapid arrival of immigrants between 1880 and 1890 made apparent the need for quick and accurate data processing. The 1880 census was a disaster. It took 9 years and $5.8 million to transfer raw data to tally sheets which were then counted by hand! The census was obsolete at the exact second it was completed. Herman Hollerith, a German immigrant, molded math, science, and engineering into the first practical "computer" to process data.
