Census Tract 2010 to PCA Crosswalk for American Community Survey (ACS) Data

Crosswalk between Census tracts (2010) and Arizona Dept. of Health Services Primary Care Areas (PCAs). This version is used to identify PCAs by tract for American Community Survey (ACS) data. If you're working with Census 2010 data, use this version instead. Why did ADHS develop two Tract to PCA conversion keys? The U.S. Census Bureau changed the tract ID for seven tracts in American Community Survey (ACS) data from the originally assigned tract id in the 2010 Census data release. As a result, two crosswalks are needed, one for Census 2010 and another for ACS data. Use the correct one depending on the source of your data.本数据集为2010年人口普查区域（Census tracts）与亚利桑那州卫生服务部（Arizona Dept. of Health Services）初级保健区域（Primary Care Areas，PCAs）之间的交叉对照表。本版本可用于基于美国社区调查（American Community Survey, ACS）数据，通过人口普查区域识别初级保健区域。若您使用的是2010年人口普查原始数据，请选用本版本。 为何亚利桑那州卫生服务部（ADHS）需开发两套人口普查区域至初级保健区域的转换对照表？美国人口普查局对美国社区调查（ACS）数据中的7个人口普查区域的区域ID进行了调整，使其与2010年人口普查数据发布时最初分配的区域ID不一致。因此需制备两套交叉对照表：一套适配2010年人口普查数据，另一套适配ACS数据。请根据您所用数据的来源选择对应的对照表。
