洛杉矶县网站关于县管委会的描述：
The five-member Board of Supervisors, created by the state Legislature in 1852, is the governing body of the County of Los Angeles. The Board appoints all department heads other than the assessor, district attorney and sheriff, which are elective positions. As a subdivision of the state, the County is charged with providing numerous services that affect the lives of all residents, including law enforcement, property assessment, tax collection, public health protection, public social services, elections and flood control.There are 88 cities within the County, each with its own city council. All of the cities, in varying degrees, contract with the County to provide municipal services. The Board of Supervisors acts as the "city council" for unincorporated areas. There are separate governing boards for air quality, water, sanitation, transportation, and education.
1852年，州立法机关创立的五人管委会，是洛杉矶县的管理主体。该委员会指定除评审员、地方检察官、县长（这些官员由选举产生）以外的所有部门首长。作为州的分区，县有责任提供很多影响全体居民生活的服务，比如执法、资产评估、税收、医疗、社会服务、选举和防洪。县内有88个市镇，每个市镇都有自己的市镇署。 这些大小不一的市镇，和县里订立契约提供市政服务。（县）管委会承担乡下市政署的角色。在空气质量、水务、环卫、交通、教育等方面有单独的管委会

洛杉矶市网站关于洛杉矶市政府的描述。
The basic law of the government of the City of Los Angeles is found in the City Charter, first adopted by a vote of the people in 1924, effective July 1, 1925, and subsequently amended from time to time. In 1999, the voters approved a new City Charter that addresses government in this new century.
洛杉矶市政府基本法记载在城市特许状里，该特许状由人民在1924年投票确认、1925年7月1日生效，1999年投票人批准了新的特许状来定位新世纪里的市政府。

由此可见，县是州政府派过来，提供基本公共服务的。类似于中国古代的县衙。
市是居民自己组织起来，从州县政府取得授权提供部分基本公共服务，并提供不属于州县服务范围内的补充公共服务。
