Hollerith Punch Card for the 1900 Census of Population, Replica

<< >>
This paper punch card was designed for use in compiling data collected in the 1900 U.S. Census of Population. It includes fields for designating enumeration district, race, sex, age, marital status, number of children, number of children living, place of birth, place of birth of parents, years in the United States, citizenship status, occupation, whether employed, and years of education.
A mark printed on the bottom edge of the card reads: IBM190916. A mark penciled on the back reads: CHARLES LOCKERBY (/) IBM / WASH. As IBM did not take that name until 1924, the card was not printed for the Census.
Compare 1988.3098.03. The punch cards with this museum number were received at the museum in 1959 from the Bureau of the Census.
