Medically underserved areas & HPSA profile
176 Medically Underserved Areas and 731 active HRSA Health Professional Shortage Area designations across Illinois.
Lower-middle density verdict
Illinois sits in the lower-middle quarter by active designations per resident. According to current HRSA Data Warehouse records, its 102 counties carry 731 active shortage designations; Cook County has the largest county count at 154, while about 49.8% of residents live in a geographic shortage county.
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.
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.
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).
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
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 sits below the national mid-pack by designations per resident with 731 active records across 102 counties. A moderate footprint still matters: a single high-score dental or mental-health record can open program geography even when the state total looks small next to denser peers.
About 49.8% of residents live in a geographic shortage county. Use the county ranking below to see which localities drive that share.

HRSA designations describe structural provider-shortage criteria and federal-program eligibility. They do not measure appointment availability, insurance coverage, care quality, or an individual patient’s access to care.
