Title: West Coast of the United States
Content:  There are conflicting definitions of which states comprise the West Coast of the United States, but the West Coast always includes California, Oregon, and Washington as part of that definition. Under most circumstances, however, the term encompasses the three contiguous states and Alaska, as they are all located in North America. For census purposes, Hawaii is part of the West Coast, along with the other four states. Encyclopædia Britannica refers to the North American region as part of the Pacific Coast, including Alaska and British Columbia. Although the encyclopedia acknowledges the inclusion of Hawaii in some capacity as part of the region, the editors wrote that "it has little in common geologically with the mainland states." Several dictionaries offer different definitions of the West Coast. Lexico restricts the West Coast's definition to "the western seaboard of the U.S. from Washington to California." However, Macmillan Dictionary provides a less specific definition as "the western coast of the U.S., along the Pacific Ocean." As for the Cambridge Dictionary, the West Coast is "the area of the Pacific coast in the U.S. that includes California."

It refers for the most part to the Southern California coastal counties of Santa Barbara, Ventura, Los Angeles, Orange, and San Diego due to the cosmopolitan "SoCal" atmosphere and location of major urban coastal centers. Of these counties only the western two-thirds of San Diego, coastal half of Ventura, most of Los Angeles and all of Orange are included. However, some sources include the coastal half of Ventura, western part of Riverside, and southwestern part of San Bernardino Counties, and the northwestern corner of Baja California, because of their proximity to the Pacific Coast and because they are in the same bio-region and watershed.
