Iowa State and Territorial Census

There were many different censuses taken in the state of Iowa. That may be due to the fact that the censuses of the nineteenth century were used to determine legislative apportionment. During that time period, public lands were quickly disposed of and many people were migrating to the area. So, it seemed necessary to keep legislative seat distribution fair by taking a census whenever there was an election.

It’s important to note that not all Iowa counties participated in every census taken in Iowa. Some censuses were specific to certain cities. Also, a large portion of the census records from that time period have not survived.

Iowa Census RecordsIowa is rich in the number of censuses taken, probably because legislative apportionment was based upon them during the nineteenth century. This was a period of rapid migration into the area and rapid disposal of public lands, therefore it was thought necessary to have a census taken almost every election in order to maintain fairness in distributing legislative seats.

Although Iowa did indeed enumerate its population frequently both in special and regular censuses, not all counties complied each time. Some enumerations are for only specific cities. Also, many of the censuses that were actually completed no longer exist.

Most of the following “head of households” census enumerations have been indexed in some form. They are listed by year and county:

  • 1836 – The Wisconsin Territorial Census includes the original counties of Dubuque and Des Moines, Iowa.

The enumeration of its members in Pottawattamie includes the standard information but adds a count of wagons and guns; number of family members ill, aged, or infirm; and number oxen, cattle, and horses. It is thought that the extended census information was part of a preparation for moving these families westward.)
