Document 9: Southern California: The state is most commonly divided and promoted by its regional tourism groups as consisting of northern, central, and southern California regions.

Another influence is the geographical phrase South of the Tehachapis, which would split the southern region off at the crest of that transverse range, but in that definition, the desert portions of north Los Angeles County and eastern Kern and San Bernardino Counties would be included in the southern California region due to their remoteness from the central valley and interior desert landscape.
