Census

Guide to using U.S. Census (Federal) material at the Connecticut State Library, both Historic and Current

Special Censuses

Special federal census schedules can provide valuable information for historians and genealogists. The special schedules for Connecticut that are available at the Connecticut State Library include:

  • Industrial (manufacturing) schedules, which include information on name of owner, location, number of employees, type and quantity of equipment, articles manufactured, and production figures
  • Agriculture schedules, which can be used to document land holdings of individuals
  • Social statistics schedules, which include brief histories and statistical information for churches, societies, clubs, and other groups as well as names and locations of cemeteries
  • Mortality schedules, which list deaths for the twelve months preceding the date of the census
  • "Defective, dependent, and delinquent" schedules which include information on "deaf-mutes", "blind", "insane", "idiots", "homeless children", "inhabitants in prison", and "pauper and indigent inhabitants"
