Census Tract 2010 to PCA Crosswalk

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 Census 2010 data. If you're working with American Community Survey (ACS) 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.
