Iowa is a U.S. state in the Midwestern United States, bordered by the Mississippi River on the east and the Missouri River and the Big Sioux River on the west. In colonial times, Iowa was a part of French Louisiana and Spanish Louisiana; its state flag is patterned after the flag of France. After the Louisiana Purchase, people laid the foundation for an agriculture-based economy in the heart of the Corn Belt.
In the latter half of the 20th century, Iowa's agricultural economy made the transition to a diversified economy of advanced manufacturing, processing, financial services, information technology, biotechnology, and green energy production. It is the 26th most extensive in land area and the 30th most populous of the 50 United States. Its capital and largest city by population is Des Moines. Nicknamed the Hawkeye State, Iowa has been listed as one of the safest states in which to live.
