The Mid-South is an informally-defined region of the United States, usually thought to be anchored by the Memphis metropolitan area.
Exact definitions vary widely and consist of at least West Tennessee, North Mississippi, Northeast Arkansas, Southern Missouri and Missouri Bootheel at a minimum.
[2] Western Kentucky, Arkansas, Middle Tennessee, Southern Missouri, Northwest Alabama, and even Eastern Oklahoma are also usually included.
[3] Mooney delineated the region as "covering West Kentucky, West Tennessee, part of the Tennessee River Valley in Alabama, the northern half of Mississippi, the Eastern half of Arkansas and southeast Missouri".
