Midwestern United States
A north-central U.S. region of industry, agriculture, and political swing states.
The Midwestern United States is one of the four census regions defined by the U.S. Census Bureau, occupying the northern central part of the country. It lies between the Northeastern and Western United States, with Canada to the north and the Southern United States to the south. Officially designated the North Central Region until 1984, the area comprises twelve states: Illinois, Indiana, Iowa, Kansas, Michigan, Minnesota, Missouri, Nebraska, North Dakota, Ohio, South Dakota, and Wisconsin. According to the 2020 census, the region’s population was nearly 69 million. Geographically, the Midwest sits on the broad Interior Plain, between the Appalachian and Rocky Mountain ranges. Major rivers include the Ohio, upper Mississippi, and Missouri. The Census Bureau divides the region into the East North Central and West North Central states.
Chicago is the largest city in the Midwest and the third-largest in the United States, with its metropolitan area holding about 9.4 million people, making it the fourth-largest in North America. Other major cities include Columbus, Indianapolis, Detroit, Milwaukee, Kansas City, Omaha, Minneapolis, Cleveland, Cincinnati, St. Paul, and St. Louis. Prominent metropolitan areas beyond Chicago include Metro Detroit, Minneapolis–St. Paul, Greater St. Louis, and the Cincinnati, Kansas City, Columbus, Indianapolis, Cleveland, and Milwaukee metro areas.
The economy blends heavy industry and agriculture, with extensive areas forming the Corn Belt, while finance, medicine, and education grow in importance. Its central location makes it a transportation hub for riverboats, railroads, trucks, and airplanes. Politically, the region contains multiple swing states, making it heavily contested in elections. Historically, the term “West” once applied here; early French settlers called the upper Mississippi watershed the Illinois Country. The Northwest Ordinance of 1787 created the Northwest Territory, bounded by the Great Lakes and the Ohio and Mississippi Rivers. Pre-Columbian cultures, including the Mississippian people, built large earthworks like Monks Mound and practiced agriculture based on maize, beans, and squash. Major Native American tribes in the Great Lakes area included the Huron, Ottawa, Ojibwe, Potawatomi, and Ho-Chunk, most speaking Algonquian languages.

Lore & Background
The Midwest occupies the north-central portion of the United States, lying on the broad Interior Plain between the Appalachian and Rocky Mountain ranges. Its twelve states—Illinois, Indiana, Iowa, Kansas, Michigan, Minnesota, Missouri, Nebraska, North Dakota, Ohio, South Dakota, and Wisconsin—are bordered by Canada to the north, the Northeastern and Western United States to the east and west, and the Southern United States to the south. Major rivers include the Ohio, upper Mississippi, and Missouri. The region is a mix of heavy industry and agriculture, with extensive areas forming part of the Corn Belt, and its central location makes it a transportation crossroads for river boats, railroads, and trucks. Chicago is the most populous city, with other large urban centers including Columbus, Indianapolis, Detroit, Milwaukee, Kansas City, Omaha, Minneapolis, Cleveland, Cincinnati, St. Paul, and St. Louis. Historically, the area was part of the Northwest Territory created by the 1787 Northwest Ordinance, bounded by the Great Lakes and the Ohio and Mississippi Rivers. The term “Midwest” emerged in the late 19th century, initially applied to Kansas and Nebraska as the civilized areas of the West. The region’s pre-Columbian history includes Paleo-American cultures from around 12,000 BCE, followed by Archaic, Woodland, and Mississippian periods. Mississippian peoples were mound-building farmers who cultivated maize, beans, and squash along river floodplains, with a major population decline around 1400 coinciding with the Little Ice Age. Major Great Lakes tribes included the Huron, Ottawa, Ojibwe, Potawatomi, Ho-Chunk, Menominee, Sauk, Meskwaki, Neutrals, and Miami, most speaking Algonquian languages.
