Key findings

What the HRSA Data Warehouse does not surface for Illinois on its own pages , computed from the retained designation mirror as of 2026-08-03. Each line carries its own denominator so it can be quoted as it stands.

  1. Cook County holds 21.1% of Illinois's 731 active designations (154 of 731).

    102 of 102 counties in this profile carry at least one active record; the remainder are zero-active on this release.

  2. 40.5% of Illinois's active designations are primary care.

    Discipline mix from state aggregates: 296 primary care, 185 mental health, 250 dental (denominator 731).

  3. Closing Illinois's active designations would take about 918 additional clinician FTEs, led by primary care.

    HRSA providers_needed summed once per HPSA id across the state: 532 primary care, 143 mental health, 243 dental. Federal gap estimate, not a practising-clinician headcount.

Corpus placement

Where Illinois sits among all 56 states and territories

Illinois carries 731 active HPSA designations for a population of 12,812,508, which is 5.7 per 100,000 residents, ranking it 33 of 56 and above 41% of states and territories, against a median of 7.3.

42 of those are county-wide geographic designations; the remainder are facility-, population- or clinic-based, which is why the county map and the designation count answer different questions.

Designation density tracks rural geography as much as unmet need: AK records 134.7 designations per 100,000 residents and NJ 1.5, because a sparsely-settled state accumulates more separate designations to cover the same population. Designations also overlap, so this counts designations, not people. Counted as distinct HRSA designation IDs, the same unit as the totals above. Computed from the designation records and county populations behind this page; states without county population data are given no placement rather than an estimated one.

Illinois Shortage Designations by Care Type

How Illinois's 731 active HRSA designations split across the three provider categories. According to KFF's May 2026 tracker, Illinois has adopted ACA Medicaid expansion. That policy context does not measure provider supply, appointment availability, or care quality.
