Sample Image
In 1885 the South Dakota State Legislature mandated that a census be taken in June of that year and every 10 years thereafter. The last census was taken in 1945. The completed cards were then sent to the Secretary of State. The census covers approximately 90% of the population.

The state census was taken in order to enumerate the population for representation purposes. Censuses are generally reliable, depending on the knowledge of the informant and the care of the census enumerator. Information may have been given to a census taker by any member of the family or by a neighbor. Some information may therefore be incorrect.

How Do I Analyze the Results?
Compare each result from your search with what you know to determine if there is a match. This may require viewing multiple records or images. Keep track of your research in a research log.

I Found the Person I Was Looking For, What Now?

 * Add any new information to your records
 * Use the age listed to determine an approximate birth date. This date along with the place of birth can help you find a birth record. Birth records often list biographical and marital details about the parents and close relatives other than the immediate family
 * Use the race information to find records related to that ethnicity such as records of the Freedman’s Bureau or Indian censuses
 * Use the naturalization information to find their naturalization papers in the county court records. It can also help you locate immigration records such as a passenger list which would usually be kept records at the port of entry into the United States
 * Birthplaces can tell you former residences and can help to establish a migration pattern for the family
 * If they are subject to military service they may have military files in the State or National Archives
 * Occupations listed can lead you to employment records or other types of records such as school records; children’s occupations are often listed as “at school”
 * Repeat this process with additional family members found, to find more generations of the family
 * Church Records often were kept years before government records were required and are a good source for finding ancestors before 1900

I Can’t Find the Person I’m Looking For, What Now?

 * Collect entries for every person who has the same surname. This list can help you identify possible relatives
 * If you cannot locate your ancestor in the locality in which you believe they lived, then try searching records of a nearby locality
 * Standard spelling of names typically did not exist. Try variations of your ancestor’s name while searching the index or browsing through images
 * Remember that sometimes individuals went by nicknames or alternated between using first and middle names, or even initials
