Jones County is a county located in the state of South Dakota. Based on the 2010 census, the population was 1,006, making it the least
populous county in South Dakota. Its county seat is Murdo. Created in 1916 and organized in 1917, it is the most recently established county
in South Dakota
As an unorganized county, Jones County was called Pratt. Lyman County, which was unorganized and heavily in debt,
persuaded Presho and Pratt Counties to join. Almost immediately the fight to separate began. In 1907 the legislature
passed a law describing how the counties should separate. The vote failed. In 1910 they voted again and lost and in 1916
they voted once again and the proposition carried. Murdo is the county seat.
