Genealogical Research Series Pamphlet No. 5

State Census Records


This pamphlet is one in a series designed to assist the genealogical researcher in using the most pertinent of related federal, state, and local governmental records in the possession of the Illinois State Archives and its Illinois Regional Archives Depository (IRAD) system. This pamphlet concerns state censuses.

State Census Records

Historical Background
The Illinois Constitution of 1818 required that a state census be taken in 1820 and every fifth year thereafter in order to determine apportionment of representation in the General Assembly. The state constitution of 1848 accepted the federal decennial censuses as the basis for apportionment but also provided for state censuses at mid-decades. Thus state censuses were conducted in 1855 and 1865. The Illinois Constitution of 1870 ended the practice of state censuses when it established the federal decennial censuses as the sole guide to reapportionment.

State censuses were taken in 1820, 1825, 1830, 1835, 1840, 1845, 1855, and 1865. Unfortunately only the 1820, 1855, and 1865 ones have survived reasonably intact. Most of the county returns for 1825, 1830, 1835, and 1845 are missing and nearly half of the 1840 state census has been lost.

Record Contents
State censuses list only the name of the head of each household. Other inhabitants simply were tallied. All of the state censuses listed below are available on microfilm for consultation at the Illinois State Archives in Springfield.

Finding Your Ancestors
Researching On Your Own

The Name Index to Early Illinois Records, located in the Archives card catalog aisle, includes entries for heads of households for state censuses through 1855. Filed separately, the index for the 1865 state census currently covers 70 counties. Because volunteers are in the process of indexing the remaining counties, an updated list should be requested at the reference desk. Index citations will enable the genealogist to reference original entries in the state censuses. The Archives also has a collection of published indexes to state censuses. Issued by local genealogical societies, these indexes cite heads of households of particular counties for various census years. Archives staff can provide a list of these published indexes.

Mail, Telephone and Internet Requests
In searching state censuses Archives staff members require the census year, the full name of the head of the household, that person’s county residence, and if possible, the township. For the 1865 census counties not yet indexed will be searched if the researcher can provide all of the above information. For this census reference staff cannot perform searches of cities exceeding 2,500 persons which have not been indexed. If a subject’s name is found, the Archives will furnish the genealogist an uncertified and unofficial photocopy of the census page on which it appears. As a result of limitations on staff research time, the Archives can research no more than two searches per inquiry. Send inquiries to: Illinois State Archives, Reference Unit, Norton Building, Springfield, Illinois 62756. Telephone: (217) 782-3553. Fax: (217) 524-3930. Submit a Request Via the Internet.
