Health professional shortage areas
HRSA, the federal Health Resources and Services Administration, designates Health Professional Shortage Areas (HPSAs): places, population groups, or facilities with too few primary care, mental health, or dental providers. An area designation covers a geographic area or a population group, such as low-income residents. A facility designation covers one site, such as a health center or clinic. Each has a score from 0 to 25 (0 to 26 for dental); a higher score means greater need.
HRSA lists 6 designated shortage rows in St. Clair County: primary care 2 (highest score 19), mental health 2 (highest score 14), and dental 2 (highest score 25). 3 cover a geographic area or population group; the other 3 are facility designations.
| Discipline | Area or population | Facility | Highest score |

About this data
County rates are CDC PLACES model-based estimates of adults, built from the CDC BRFSS survey and Census population data. State and US figures are BRFSS survey results for the same year. They are not averages of counties, and small differences may not be meaningful.
Shortage rows are HRSA designations with status Designated. Scores run from 0 to 25 (0 to 26 for dental); a higher score means greater need. Hospitals are acute care and critical accesshospitals CMS lists in the county, with 30-day rates of unplanned readmission. Health centers are active HRSA-funded and look-alike sites.
Rural health plan initiatives are copied as the state wrote them. Nothing here is medical advice.
