Illinois, State Census, 1865

What is in This Collection?

This collection contains a name index & images of the Illinois state census taken on 3 July 1865. The following counties are missing:

  • Gallatin
  • Monroe
  • Part of Mason
  • Part of Tazewell

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 1865 exist for 99 of the 102 counties.

This census counted and gathered information about the population in 1865. The census was compiled to obtain a count of the population to determine how many representatives the state would send to Congress.

Reliability of the information in the census is determined by the accuracy of the knowledge of the informant, which could have been any member of the family or even a neighbor.

Additional records and/or images may be added to this collection in the future.
