Census Municipal Boundaries 2021

Incorporated Places are those reported to the Census Bureau as legally in existence as of January 1, 2019, under the laws of their respective states. An incorporated place provides governmental functions for a concentration of people, as opposed to a minor civil division (MCD), which generally provides services or administers an area without regard, necessarily, to population. An incorporated place usually is a city, town, village, or borough, but can have other legal descriptions. CDPs are the statistical counterparts of incorporated places. CDPs are settled concentrations of population that are identifiable by name but not legally incorporated under the laws of the state in which the CDPs are located. The Census Bureau defines CDP boundaries in cooperation with local partners as part of the PSAP. CDP boundaries usually coincide with visible features or the boundary of an adjacent Incorporated Place or another legal entity boundary. CDPs have no legal status and do not have officials elected to serve traditional municipal functions. CDP boundaries may change from one decennial census to the next with changes in the settlement pattern; a CDP with the same name as in an earlier census does not necessarily have the same boundary.建制属地（Incorporated Places）指截至2019年1月1日，符合所在州法律规定、合法存续并向美国人口普查局（Census Bureau）报备的区域。建制属地为聚居人口提供公共治理职能，与县级以下民政分区（minor civil division, MCD）存在本质区别：后者通常仅提供公共服务或管理辖区，并不必然以人口聚居为前提。建制属地通常表现为市、镇、村或自治镇，但也可采用其他法定称谓。普查指定地区（Census Designated Places, CDPs）是建制属地的统计对应实体，指拥有可识别名称的人口聚居区域，但依据其所在州的法律，并未获得合法建制地位。美国人口普查局会同地方合作伙伴，作为PSAP的组成部分划定CDP的边界。CDP的边界通常与可见地理特征、邻近建制属地的边界，或其他法定实体的边界保持一致。普查指定地区不具备法定地位，亦无经选举产生的官员履行传统市政职能。其边界会随聚居格局的变化在每十年一次的人口普查周期间发生调整；名称与此前普查中一致的普查指定地区，其边界未必与此前相同。
