1880 United States Census
The United States Census 1880 was the tenth census of the United States since 1790. As a result of counting a population number was for the U.S. to date, August 1, 1880 determined by 50,189,209 inhabitants ( 30.2% more than at the Census 1870).
As with the 1870 Census data was collected by many. The questionnaire in 1880 consisted of five parts, of which four were from the sensing field staff. The first part concerned the demographic data, part 2, the mortality ( such as 1870, marital status, birthplace of parents, length of stay in the United States, place of discovery of the disease or of death ), the third part of agricultural data ( where applicable). The fourth part has not been recognized by the detection staff, but by separate staff required. It was the tax and debt burden and data on infrastructure. Part 5 was recorded conventionally and involved the craft ( if applicable).
For the first time women were allowed to perform the survey. The data are still available as microdata today. Since the counting of data took more than seven years, Herman Hollerith was commissioned to develop a calculator for the 1890 census. In addition, the high increase in population for Census 1870 was doubted and suspected that it had come in the 1870 census to an under-estimation.
By the 1880 census, the Alabama paradox was uncovered or discovered.
