Edgar County lists county of births on the 1850 census. In addition to the generally available indexes in print and online (see page 3), a card index for Cook County developed by Bernice C. Richard is at the Illinois State Archives with microfilm copies at Newberry Library and National Archives—Great Lakes Region. Printed indexes for the same census year have been published by local county organizations. Over 1,000 cards in the “O” section for the Soundex for the 1880 federal population schedules were omitted. All of the aforementioned are at the Illinois State Historical Library (see Archives, Libraries, and Societies). Only Mound Township of McDonough County survives from the 1890 census. Many larger genealogical libraries have print indexes to Illinois federal state censuses through 1870. See pages 16-17 for a full discussion of online sources.


Two territorial censuses were taken for the Illinois populace in 1810 (as Indiana Territory) and 1818 (as Illinois Territory). The 1810 extant returns only include Randolph County in the southern portion of the state. What remains of both censuses have been indexed by AISI (see page 3). Originals are at the Illinois State Archives.


The state censuses will list only the head of family by name, followed by numerical totals in age categories for the balance of the household. The following enumerations were taken by the state and remain extant.

1820—Eighteen counties, which included all of Illinois except Edwards County

1825—Edwards, Fulton, and Randolph counties only

1830—Morgan County only (includes present counties of Cass, Morgan, and Scott)

1835—Fayette, Fulton, Jasper, and Morgan counties (includes present counties of Cass, Morgan, and Scott)

1840—Thirty-five counties included. Consult Descriptive Inventory of the Archives of the State of Illinois (see Illinois Archives, Libraries, and Societies) for list of counties.

1845—Cass, Madison, Putnam, and Tazewell counties only

1855—For all counties except Carroll, Champaign, Franklin, Gallatin, Henry, Jefferson, Lake, Stark, Will, and Woodford

1865—For all counties except Gallatin, Mason, Monroe, and Tazewell (Elm Township in Tazewell County has survived)

The “Name Index to Early Illinois Records” (index to state and federal census records 1810–55 and other government documents) is available on interlibrary loan, by surname, from the Illinois State Library and through The Family History Library (FHL) in Salt Lake City.

Some city census enumerations were made in Illinois in the 1930s. There is also a microfilmed military census, enumerated in 1862, by county, which lists men eighteen to forty-five years of age. It can be borrowed on interlibrary loan from the Illinois State Archives.
