The Government of Los Angeles County is defined and authorized under the California Constitution, California law, and the Charter of the County of Los Angeles. Much of the Government of California is in practice the responsibility of county governments, such as the Government of Los Angeles County. The County government provides countywide services such as elections and voter registration, law enforcement, jails, vital records, property records, tax collection, public health, health care, and social services. In addition the County serves as the local government for all unincorporated areas.
