Data collected

Five schedules were authorized by the 1880 Census Act, four of which were filled out by the enumerators:
from the U.S. Census Bureau * Schedule 1 (Population), which was similar to that used for the United States Census, 1870, previous census, with a few exceptions. * Schedule 2 (Mortality), which used the same inquiries as in 1870, and added inquiries to record marital status, birthplace of parents, length of residence in the United States or territory, and name of place where the disease was contracted, if other than place of death. * Schedule 3 (Agriculture), which greatly expanded inquiries concerning various crops (including acreage for principal crop), and included questions on farm tenure, weeks of hired labor, annual cost for fence building and repair, fertilizer purchases, and the number of livestock. * Schedule 5 (Manufacturing), which expanded to include information on the greatest number of hands employed at any time during the year, the number of hours in the ordinary work day from May to November and November to May, the average daily wages paid to skilled mechanics and laborers, months of full-and part-time operation, and machinery used. Schedule 4 (Social statistics) was the responsibility of experts and special agents, rather than the enumerators. The majority of the data came from correspondence with officials of institutions providing care and treatment of certain members of the population. Experts and special agents also were employed to collect data on valuation, taxation, and indebtedness; religion and libraries; colleges, academies, and schools; newspapers and periodicals, and wages. Special agents were also charged with collecting data on specific industries throughout the country, and included the manufactures of iron and steel; cotton, woolen, and worsted goods; silk and silk goods; chemical products and salt; coke and glass; shipbuilding; and all aspects of fisheries and mining, including the production of coal and petroleum.
