Founded in the 1950′s and Incorporated in 1991, the South Dakota Association of County Officials is geared toward promoting the general welfare of county officials and to establish more uniform methods of procedure in those county offices. Our goal is to serve in an advisory capacity to the Legislature on matters of county administration and procedure.
South Dakota is divided into sixty-six counties which range in population from 124,000 in Minnehaha to 1,300 people in Jones County. Most of the current county boundaries were originally established in the middle and latter part of the nineteenth century, and some in the early part of the twentieth century. At one time, South Dakota consisted of many more counties than the present day sixty-six. But, as transportation improved in South Dakota it became easier to travel to the county seat and the population shifted.
The South Dakota Association of County Officials (SDACO) is the professional association of Auditors, Treasurers, and Registers of Deeds for all 66 South Dakota counties. The mission of SDACO is to promote effective and efficient county government for the citizens of South Dakota. Founded in the 1950’s, and incorporated in 1991, SDACO works to ensure excellence in service and uniform procedures by the state’s elected county officials
