PCSA Data Download – 2010 (Census Tract Basis)

The goal of the Primary Care Service Area (PCSA) Project is to provide information about primary care resources and populations within small standardized areas that reflect patient utilization patterns. This is the first release of PCSA data using the new PCSA 3.1 boundaries, based on 2010 census tract geography.

The PCSA data are in DBF format. With the exception of the Centers for Medicare & Medicaid Services (CMS) data, missing data values are displayed as -99. In the CMS data, suppression rules apply to the Medicare variables; suppressed data values are displayed as -999.

The 2010 edition of the PCSA database contains nationwide data on U.S. primary health care resources, populations and utilization, compiled and presented in newly developed areas of analysis (PCSAs, version 3.1) and related to other geopolitical units. These PCSAs were developed by aggregating groups of 2010 Census Tracts.
