Center is a city in Oliver County, North Dakota, United States. It is the county seat of, and the only incorporated place in, Oliver County. Center was founded in 1902. The city was named from its location near the geographical centre of Oliver County. Coincidentally, it has also been calculated to be the geographical centre of North America. Peter Rogerson, a professor of geography at the University at Buffalo in New York, used new scientific methods and the azimuthal equidistant projection to calculate the "geographic center" of the North American continent. By some extraordinary coincidence, he found that Center, North Dakota, is the continent's geographical centre. Southwest of Center, there is a large open air coal mine. Southeast of Center, at Nelson Lake there is a large power plant. West of Nelson Lake is situated the Square Butte high-voltage direct current transmission line's static inverter.
Center has a population of over 571 people.
