Regional definitions vary slightly among sources. This map reflects the Midwestern United States as defined by the
U.S. Census Bureau, which is followed in many sources.
The Midwestern United States (or Midwest) is a name for the north-central states of the United States of America. The Midwest is composed of Nebraska, Indiana, Illinois, Iowa, Kansas, Minnesota, Missouri, Michigan, North Dakota, Ohio, South Dakota and Wisconsin. Oklahoma and Kentucky are occasionally considered Midwestern, but this definitely is questioned by scholars, whom refer to those regions, along with Missouri to be border states - those consisting of southern and Midwestern traits.
Chicago, Illinois, is the largest city in the Midwest, and third largest city nationwide
