- Description
- These paper punch cards have the fields used in the U.S. Census of population in 1930. Each is marked: POPULATION, 1930. Each is also marked: TM2021.
- The cards were similar in past ones in that they record the age, gender, race, marriage status, and education status of an individual. The 1930 punch card changed from the 1920 punch card in three ways. The first was the use of a more standardized 12-key punch, which required changing some of the code symbols to make the card puncher’s job a bit easier. The second was a different look and column spacing of the card. The third was changes in the content. Some areas, like household head, were moved to the family card. The columns were numbered and labeled on the bottom of the card.
