By residents, the state is generally divided into North Texas, East Texas, Central Texas, South Texas, West Texas and, sometimes, the Panhandle, but according to the "Texas Almanac", Texas has four major physical regions: Gulf Coastal Plains, Interior Lowlands, Great Plains, and Basin and Range Province. This has been cited as the difference between human geography and physical geography, although the fact that Texas was granted the prerogative to divide into as many as five U.S. states may be a historical motive for Texans defining their state as containing exactly five regions.
