Primary Care Areas

Primary Care Areas (PCAs) are geographic regions created by the Arizona Department of Health Services (ADHS). They are designed to represent the communities of the state while maintaining populations conducive to statistical/spatial analysis. PCAs are built from US Census Tracts and are updated every Census using a repeatable rule based methodology intended to preserve community boundaries, provide population numbers conducive to statistical analysis, account for demographic variation and represent common utilization of primary care services. The creation and maintenance of PCAs is required by Arizona Administrative Code R9-24-204 for use in designating Medically Underserved Areas. PCA Summary 126 AZ Primary Care Areas 55 in metro Phoenix area 20 in metro Tucson area Populations of 10,000-200,000 (except tribal areas) Areas no greater than 7,500 square miles (except tribal areas) Reflect existing communities, including cities, towns, municipal planning areas (i.e. City of Phoenix Villages), and Tribal lands (reservations) UPDATE FREQUENCY: Every Decennial Census/10 years初级保健区域（Primary Care Areas, PCAs）是亚利桑那州卫生服务部（Arizona Department of Health Services, ADHS）划定的地理区域。其设立目标是在保障人口规模适配统计与空间分析的前提下，精准代表该州各社区群体。PCAs基于美国人口普查区（US Census Tracts）构建而成，每一轮人口普查周期均会依据可重复的规则化方法进行更新，该方法旨在保留社区边界、提供适配统计分析的人口数据、考量人口结构差异，并体现初级保健服务的普遍使用情况。PCAs的创建与维护需遵循《亚利桑那州行政法典》R9-24-204的规定，用于划定医疗服务欠缺地区（Medically Underserved Areas）。 PCA概要：亚利桑那州共计126个初级保健区域，其中凤凰城都会区包含55个，图森都会区包含20个；区域人口规模介于10000至200000之间（部落区域除外）；单区域面积不超过7500平方英里（部落区域除外）；需如实反映现有社区形态，包括城市、城镇、市政规划区域（例如凤凰城社区，City of Phoenix Villages）以及部落土地（即保留地，Tribal lands）。 更新频率：每十年一次，与十年一次人口普查周期同步。
