Historical Background
Federal censuses for the state of Iowa begin with 1850 and were taken every ten years through 1990. See the United States Research Outline for more information about nationwide census records and indexes.

Census records from 1850 on can show names of each member of the household, his or her age, state or country of birth, occupation and race. Censuses can also give clues about marital status, marriage dates, death dates, immigration and naturalization information, migration patterns, previous residence, adoptions, and divorces. (See the United States Research Outline for more details.) Censuses for 1840 and earlier list only heads of families.

Most families were listed when a census taker made his visits, making these records rich in clues. Other persons in the county with the same surname may be related to each other. Statewide indexes can also help to locate families when only the state where they lived is known.

Indexes
The 1850, 1860, and 1870 federal censuses have statewide, head-of-household indexes (in books). These were compiled by various organizations. If an ancestor does not appear in one index, check another for the same year as the handwriting may not have been deciphered correctly.

The 1880 (partial), 1900, and 1920 censuses have Soundex (phonetic) indexes on microfilm.

The 1910 census does not have a Soundex index for Iowa; however, if you know the town or city where your ancestor lived, you can find the appropriate county, enumeration district number, and Family History Library film number by looking in the following source:

Buckway, Eileen G., comp. U. S. 1910 Federal Census: Unindexed States: A Guide to Finding Census Enumeration Districts for Unindexed Cities, Towns, and Villages. Salt Lake City, Utah: Family History Library, 1992. (FHL book 973 X2bu 1910; fiche 6101340)

Special Censuses
Mortality Schedules, 1850–1880

The 1850, 1860, 1870, and 1880 censuses have mortality schedules. These schedules list the names of persons who died during the year preceding the census. Mortality schedules contain information on a person’s age, state or country of birth, month of death, cause of death, number of days ill, race, occupation, and for 1880, parents’ birthplaces.

The State Historical Society in Des Moines and Iowa City and the Family History Library have copies of the mortality schedules.


 * 1850 (FHL film 1421006)
 * 1860 (FHL film 1421007)
 * 1870 (FHL films 1421008-10)
 * 1880 (FHL films 1421011-14)

Like the census, these records are arranged by county and then by town.

The 1850 census mortality schedule has been indexed in:

Jackson, Ronald Vern. ''Iowa 1850 Mortality. North Salt Lake, Utah: Accelerated Indexing Systems, 1987''. (FHL book 977.7 X2j 1850).
