There are Industry and Agriculture Schedules 1850, 1860, 1870 and 1880. The Mortality Schedules for the years 1850, 1860, 1870 and 1880. The Union Veterans Schedules exist for 1890.
Indiana federal census records until 1930 can be found at both the Allen County Public Library and the Indiana State Library.
However, the 1850 census missed several of the families living in rural areas because routes were not passable and weather was bad at the time the census was taken. That year’s agricultural schedule is more accurate because it was taken when the weather was better.
The 1860 census has been compiled into a fully searchable index by the Indiana Historical Society. A researcher could, for instance, easily find the place of birth for Indiana ministers by searching the index. Researchers can purchase a copy on microfiche from the Indiana Historical Society.
Indiana State and Territorial Census
There are no Indiana state census records available. However, the 1807 Indiana Territory Census is still extant. There are available records of state enumerations of males over the age of 21 from 1820 onward, but they do not include names.
