West Bay

Used to describe San Francisco and the Peninsula (San Mateo County) by people who live in the East Bay (Alameda and Contra Costa Counties). The term is meant to bring awareness to the fact that many people from SF and the Peninsula often don’t seem to realize that the East Bay exists until they can no longer afford housing there and decide to move to the East Bay.

People that grew up in Bay Area suburbs with >$100k household median income:
