The net effect of the many changes from the 1880 census: the larger population, the data items to be collected, the Census Bureau headcount, the scheduled publications, and the use of Hollerith's electromechanical tabulators, was to reduce the time required to process the census from eight years for the 1880 census to six years for the 1890 ...
Invented by Herman Hollerith, the machine was developed to help process data for the 1890 U.S. Census. Later models were widely used for business applications such as accounting and inventory control. It spawned a class of machines, known as unit record equipment, and the data processing industry.
"Using Hollerith's punchcard equipment, the Census Office was able to complete tabulating most of the 1890 census data in 2 to 3 years, compared with 7 to 8 years for the 1880 census. It is estimated that using Hollerith's system saved some $5 million in processing costs" [ 4 ] in 1890 dollars even though there were twice as many questions as ...

The processing of the 1880 census data took so long (eight years) that the Census Bureau contracted Herman Hollerith to design and build a tabulating machine to be used for the next census. [8] [9] The 1880 census also led to the discovery of the Alabama paradox. Source: Table I, Population of the United States, by States and Territories [10]

The concept of automated data processing had been born. In 1890, Herman Hollerith invented the mechanical tabulating machine, a design used during the 1890 Census which stored and processed demographic and statistical information on punched cards.
