Illinois, State Census, 1855 - FamilySearch Historical Records

What is in This Collection?
The collection consists of a name index for the Illinois State Census. This census counted and gathered information about the population in 1855. The census was compiled to obtain a count of the population to determine how many representatives the state would send to Congress. The state constitution of 1848 accepted the federal decennial censuses as the basis for apportionment of representatives, but also provided for state censuses at mid-decades. As a result state censuses were conducted in 1855 and 1865. The state constitution of 1870 ended the practice of state censuses. Census returns for 1855 exist for 90 of the 100 counties. The information was handwritten on pre-printed sheets. Schedules do not exist for the following counties: • 3 Jo Daviess County returns for the 1855 are found in the Ancestry "Illinois, State Census Collection, 1825-1865". Microfilm copies of original records are available at the Family History Library and at family history centers.
