Overview
The tenth decennial census of the United States was conducted in June 1880. Administered by the Office of the Superintendent of the Census under Francis Amasa Walker, it produced the official population count and accompanying social and economic data used by government and researchers. The total resident population returned was 50,189,209, an increase of about 30.2 percent from 1870.
Scope and questions
Enumerators collected detailed information on individuals and households, using separate census schedules for population and for key economic subjects such as agriculture and manufacturing. Typical population details recorded included name, age, sex, race, relationship to head of household, marital status, place of birth and parents' birthplaces, occupation, and indicators such as literacy and certain disabilities. These items helped lawmakers and analysts track demographic change, migration, and labor patterns.
Administration and innovations
The 1880 enumeration is notable for two administrative developments. For the first time women were appointed and served openly as enumerators, reflecting a gradual widening of opportunities in federal hiring. The census continued to refine its schedules and aggregation procedures, though most tabulation was still manual; later technological advances in the 1890s would transform processing.
Major findings and significance
The population breakpoint at roughly fifty million symbolized rapid national growth in the post‑Civil War era. The results documented accelerating urbanization and industrial expansion in the Northeast and Midwest, increased immigration and western settlement, and changing occupational structures. Policymakers and businesses used these data for representation, infrastructure planning, and economic decision making.
Historical context and comparisons
The 1880 count built on earlier censuses and provides a bridge between Reconstruction‑era demographics and the industrializing United States of the late nineteenth century. It is commonly referenced in comparison with the 1870 census to measure growth; contemporaneous summaries and later analyses help interpret regional shifts and social trends.

Records, research, and access
Original schedules and compiled tables from 1880 are preserved in federal records and have been microfilmed and digitized in many projects, making the data available to genealogists, historians, and demographers. For the headline population figure consult primary sources such as the official reports population report and for earlier comparisons see the 1870 enumeration 1870 census. Researchers should note variations in terminology and geographic boundaries when comparing censuses across decades.
