The Health Resources and Services Administration (HRSA) collects detailed oral health services data aggregated by geographic divisions called Primary Care Service Areas (PCSAs). According to HRSA, “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.”
HRSA PCSA estimates reflect a variety of sources and time periods. The data below were retrieved from the HRSA data portal in October 2016. Additional data processing provided by Rob Paral & Associates.
