Federal Census Indices

Our collection includes indices of United States Federal Census records for Lake County for 1860, 1870, 1880, 1900, 1910, 1920, and 1930. These indices give a person's name (as determined by the indexer), age, sex, race, their enumeration district, page number, and line number. This information helps locate the exact page of the census, which we have available on our microfilm computer in the library. Federal censuses are available online through genealogy websites such as FamilySearch.org and Ancestry.com.

Colorado State Census Index

State censuses were often taken in years between the federal censuses. Colorado conducted the state census on June 1, 1885. Our Colorado State Census Index for 1885 includes each person's name (as determined by the indexer), age, sex, enumeration district (ED), page number, and line number. The information from the index helps locate the exact page of the census, which we have available on our microfilm computer in the library. The Colorado State Census is also available online through genealogy websites such as FamilySearch.org and Ancestry.com. This census has become a highly valuable source as it provides a wealth of information that would otherwise be found in the 1890 Federal Census.
