HPSA Score Estimator

Enter an area's population and primary-care provider FTEs to see the live population-to-provider ratio and whether it would clear HRSA's geographic-HPSA threshold.

This is an unofficial estimate of the ratio criterion only. HRSA's full HPSA score also weights poverty, travel time to the nearest source of care, and infant mortality. See our methodology for the thresholds used.

Resident population of the service area being evaluated.

Count physicians, NPs, and PAs delivering primary care as FTEs (one half-time clinician equals 0.5).

Used only as a high-need flag. Areas with 20% or more in poverty use the lower 3,000:1 threshold.

How this estimate works

A geographic primary-care HPSA designation from HRSA generally requires a population-to-provider ratio of at least 3,500 people per full-time-equivalent primary-care provider. Where an area shows high need (for example 20 percent or more of the population below the poverty line), HRSA may designate at a ratio of 3,000 people per provider. The tool divides the population you enter by the provider FTEs you enter, then compares the result to those thresholds.

The band shown is a guide only. The official HPSA score (0 to 25 for primary care) is a weighted index that also accounts for the percent of the population below the federal poverty level, travel time or distance to the nearest source of accessible care outside the area, and the infant mortality rate or low-birth-weight rate. A higher HPSA score generally signals greater need and affects funding and recruitment priorities.

This calculator does not pull live HRSA data and does not produce an official designation. For a binding determination, work with your State Primary Care Office and review the criteria at HRSA's shortage-designation pages. For guidance only, not medical or eligibility advice.

Every figure on PlainHealthAccess is rendered directly from HRSA source data, no number is typed in by an editor. This calculator applies HRSA's published population-to-provider threshold (3,500:1 general, 3,000:1 high-need) entirely in your browser; it does not submit your inputs anywhere.
