Which state is ranked lowest in healthcare?
Alaska and Mississippi are most frequently ranked as the lowest overall states for healthcare in recent major analyses.
Lowest-Ranked States
Recent reports from national health organizations place several states at the very bottom based on cost, access, and health outcomes:
- Alaska: Ranked as the overall worst state (#51 including D.C.) by WalletHub's Healthcare Analysis, primarily driven by some of the highest monthly insurance premiums in the country.
- Mississippi: Frequently placed at or near the bottom (50th among states) due to the nation's highest infant mortality rate, low physician-per-capita counts, and poor overall health outcomes.
- Georgia, Texas, and West Virginia: Consistently round out the bottom five in multiple studies due to high uninsured rates (particularly in Texas), care avoidance over costs, and limited rural healthcare access.
Key Factors in Low-Ranked States
- Healthcare Access: Shortages of primary care physicians, dentists, and hospital beds per capita.
- Cost and Coverage: High insurance premiums or large populations avoiding medical visits due to high deductibles and uninsured rates.
- Health Outcomes: Higher rates of chronic conditions like heart disease, stroke, and high infant mortality.
