Primary Care Service Areas Data Download – 2005-2006 (ZIP Code 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. The HRSA Data Warehouse (HDW) receives PCSA data from Dartmouth Medical School.

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 PCSA 2006 data contain nationwide data on U.S. primary health care resources, populations and utilization, compiled and presented with reference to new areas of analysis (PCSAs, version 2.1) developed following the 2000 Census and related to other geopolitical units. These PCSAs were developed by aggregating ZIP Code Tabulation Areas (ZCTAs).

PCSA Level Data: HRSA Update AMA Data – Physician Characteristics 2006 (5,369 KB)
Physician characteristics are derived from 2006 American Medical Association Physician Master file (AMA MF). Characteristics of primary care physicians (family physicians, general internists, and pediatricians), specialists, obstetricians/gynecologists are provided at ZCTA and PCSA levels. Physician supply (unadjusted and age-sex adjusted rates per capita) is calculated at the PCSA-level only. The method for calculating age-sex adjusted supply is based on the method as described in the Dartmouth Atlas of Health Care, 1999. (www.dartmouthatlas.org).

The ZCTA level file contains 32,011 ZCTAs with 41 variables. The PCSA level file contains 6,542 PCSAs with 54 variables.

Due to the limit on the number of columns that a DBF can contain, the data for these subjects have been split into multiple files for each summary level. The ZCTA summary level comprises 460 unique variables; the PCSA summary level has 677.

The ZCTA level data file (File 1) contains 218 variables including 12 header variables (identification and total population variables). The ZCTA level data file (File 2) contains 254 variables with the same 12 header variables. The PCSA level data file (File 1) contains 215 variables including 9 header variables. The PCSA level data file (File 2) contains 251 variables with the same 9 header variables. The PCSA level data file (File 3) contains 229 variables with the same 9 header variables.
