1890 United States census

The 1890 United States census was taken beginning June 2, 1890. The census determined the resident population of the United States to be 62,979,766, an increase of 25.5 percent over the 50,189,209 persons enumerated during the 1880 census. The data reported that the distribution of the population had resulted in the disappearance of the American frontier.

This was the first census in which a majority of states recorded populations of over one million and the first in which three cities, New York City, Chicago, and Philadelphia, recorded populations of over one million. The census also saw Chicago rise in rank to the nation's second-most populous city, a position it would hold until Los Angeles, the 57th-most populous city as of 1890, supplanted it in 1990. This was the first U.S. census to use machines to tabulate the collected data.

Most of the 1890 census materials were destroyed on January 10, 1921, when the Commerce Department building caught fire, and in the subsequent disposal of the remaining damaged records.

Methodology

The 1890 census was the first to be compiled using methods invented by Herman Hollerith and was overseen by Superintendents Robert P. Porter (1889–1893) and Carroll D. Wright (1893–1897). Data was entered on a machine readable medium (punched cards) and tabulated by machine. Changes from the 1880 census included the larger population, the number of data items to be collected from individuals, the Census Bureau headcount, the volume of scheduled publications, and the use of Hollerith's electromechanical tabulators.
