|North Dakota is one of the least populated states in the United States. It had an estimated population of just over 640,000 residents as of 2008, which gave it 48th position among the most populous states of the country. In terms of geographical expanse, it is the 19th largest with a total area of 70,760 square miles. Situated in the Midwestern and Western regions of the nation, the state is bounded by Minnesota on the east, Montana on the west, South Dakota on the south and Canadian provinces of Manitoba and Saskatchewan on the north. Geographically, North Dakota is almost at the center of the North American Continent. The Red River flows through the eastern part of the state while the western part is largely dominated by the Missouri River, which forms Lake Sakakawea near the Garrison Dam. Red River Valley formed by the Red River provides fertile farmland to the state. Agriculture is largely the mainstay of the economy. The Dakota Territory was broken up to form a separate state by the name of North Dakota, which joined the Union in 1889 as the 39th state of the USA. The largest city is Fargo and the capital is Bismarck.
