Collection Contents
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.
