Arkansas is the 29th largest by area and the 33rd most populous of the 50 United States. The capital and most populous city is Little Rock, located in the central portion of the state, a hub for transportation, business, culture, and government. The northwestern corner of the state, such as the Fayetteville–Springdale–Rogers Metropolitan Area and Fort Smith metropolitan area, is a population, education, and economic center. The largest city in the state's eastern part is Jonesboro. The largest city in the state's southeastern part is Pine Bluff.
The state takes its name from the Ohio River. The name originated from the Iroquois language word ohi-yo, meaning "great river" or "large creek". Partitioned from the Northwest Territory, the state was admitted to the Union as the 17th state (and the first under the Northwest Ordinance) on March 1, 1803. Ohio is historically known as the "Buckeye State" after its Ohio buckeye trees, and Ohioans are also known as "Buckeyes".
