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.
