Key findings

What the HRSA Data Warehouse does not surface for Sioux County, IA on its own pages , computed from the retained designation mirror as of 2026-08-15. Each line carries its own denominator so it can be quoted as it stands.

  1. Peak HPSA score 23.0 clears HRSA's 17-point high-priority line.

    Scores at or above 17 on the 0–25/26 scales open NHSC placement priority for the matching provider type; eligibility still follows the designated area, not the county boundary alone.

  2. Closing Sioux County's active designations would take about 3.3 additional clinician FTEs, with mental health the largest gap.

    HRSA providers_needed summed once per HPSA id (no double-count across status rows): 3.3 mental health. This is the federal gap estimate, not a headcount of practising clinicians.

  3. 50% of Sioux County's 4 active designations are mental health.

    Discipline mix from designated HPSA records only: 1 primary care, 2 mental health, 1 dental (denominator 4).

Moderate-burden reading for Sioux County

Peak severity leads this reading: Sioux County's highest active HPSA score is 23.0, clearing HRSA's 17-point high-priority line. Dental care carries Sioux County's deepest shortage reading, 23.0 on HRSA's 0–26 dental scale, past the 17-point line HRSA uses to open National Health Service Corps placement and enhanced Medicare reimbursement. Primary care reads 16.0 of 25; Mental health reads 19.0 of 25. The county also sits inside a Medically Underserved Area, indexed at 58.4, and the lower the index, the greater the measured need.

Sioux County sits in the middle of the national designation-volume distribution (above 44% of counties) with 4 active records. That is enough for a formal shortage footprint without landing in the heaviest US tier. Compare the three discipline counts (1/2/1) before assuming every care category is equally short.

Sioux County falls in the upper half of IA counties by active-designation volume, at rank 47 of 99. For moderate counties, the useful move is usually a state peer check plus the score cards above, not a national superlative claim.
