California Code, Financial Code - FIN § 5105

“Community” means a centralized area or locality in which a body of inhabitants is gathered in one group having common residential, social, or business interests. The term does not necessarily mean a municipal corporation or other political subdivision. A community need not be limited by lines and boundaries. A city, village, town, or other governmental unit, either incorporated or unincorporated, may constitute one community, but a large, populous area under one or more forms of government may be composed of several communities.
