Born in Greece or Turkey - 1905, 1915, 1925, 1935, 1945 South Dakota State Census

South Dakota State Census documents for the years 1905, 1915, 1925, 1935, 1945 are available through various organizations on the internet.  

Hint:  If you can't find your ancestors in one database, don't forget to check other local or genealogy company databases.  They each do their own indexing and searches may have very different results.  Also, these companies don't all have the same contracted access to a group of documents.

I have included results from Ancestry.com , FamilySearch.org , and MyHeritage.com

Detailed descriptions for each census can be found on the FamilySearch Wiki - https://www.familysearch.org/wiki/en/South_Dakota_Census
