The heartland, when referring to a cultural region of the United States, is the central land area of the country,[1] usually the Midwestern United States[2] or the states that do not border the Atlantic or Pacific oceans,[3] associated with mainstream or traditional values, such as economic self-sufficiency, conservative political and religious ideals, and rootedness in agrarian life.[2]
The US Census Bureau defines the Midwest as consisting of 12 states: Illinois, Indiana, Iowa, Kansas, Michigan, Minnesota, Missouri, Nebraska, North Dakota, Ohio, South Dakota, and Wisconsin. Portions of other non-coastal states can be included in the region as well. These may include eastern portions of the Mountain States (Colorado, Utah, Idaho, Montana, and Wyoming) and northern portions of some Southern states, such as Arkansas, Kentucky, Oklahoma, Tennessee, and West Virginia.
