Oliver County is a county located in the U.S. state of North Dakota. As of the 2020 census, the population was 1,877.[1] Its county seat and only city is Center.[2]

History[]

The Dakota Territory legislature created the county on April 14, 1885, with territory partitioned from Mercer County. It was named for Harry S. Oliver of Lisbon, North Dakota (1855-1909), a Republican politician and member of the Dakota Territory House of Representatives at the time. The county government was organized on May 18, with Sanger (then known as "Bentley") as county seat. The seat was moved to Center in 1902.[3][4]

Oliver County is included in the Bismarck, North Dakota Metropolitan Statistical Area.

Geography[]

The northeastern/eastern boundary of Oliver County is delineated by the Missouri River as it flows southeastward after leaving Lake Sakakawea. The county terrain consists of rolling hills, mostly devoted to agriculture.[5] The terrain slopes to the east, with the highest point a hill near its southwestern corner, at 2,382' (726m) ASL.[6] The county has a total area of 731 square miles (1,890 km2), of which 723 square miles (1,870 km2) is land and 8.7 square miles (23 km2) (1.2%) is water.[7] It is the fifth-smallest county in North Dakota by area.

By sheer coincidence, the county seat, Center, named for being near the geographical center of the county, has also been calculated to be the geographic center of North America.[8]
