The West South Central states, colloquially known as the South Central states, is a region of the United States defined by the U.S. Census Bureau as covering four states: Arkansas, Louisiana, Oklahoma, and Texas. The West South Central or South Central region is located within the Southern United States and Gulf Coast regions, bordering the Mountain states and Midwestern U.S. regions to its north and west. The Gulf of Mexico is to the south of the region. Houston is the South Central's largest city, and the Dallas–Fort Worth–Arlington metropolitan statistical area is the region's largest metropolis.
A geographically diverse region, the southern portion of the states are covered by coastal plains and swamps, while the remainder is covered by forests such as the Cross Timbers, hills and mountains, and deserts near the Texas–Mexico border.
