The first national atlas of the United States, titled the Statistical Atlas of the United States Based on the Results of the Ninth Census 1870, was published in 1874. [1] Francis A.

The results from the census were used to determine the apportionment for the 48th, 49th, 50th, 51st, and 52nd sessions of the United States Congress. 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.
The tabulating machine was an electromechanical machine designed to assist in summarizing information stored on punched cards. 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.
