Nursing Home Star Ratings by State
20% of US nursing homes carry CMS's lowest 1-star rating — and only 21% earn the top 5 stars. We analyzed the CMS overall star rating for 14,572 Medicare-certified nursing homes to map where care quality is weakest, which states rank worst, and which large facilities sit at the bottom. Updated annually against the latest CMS Care Compare release.

Methodology
Figures come from the CMS Care Compare skilled nursing facility (SNF) dataset — the official Medicare quality program. The overall star rating runs from 1 (much below average) to 5 (much above average) and blends health inspections, staffing, and quality measures. We include every Medicare-certified nursing home with a published overall rating (14,572 facilities).
State averages cover states with at least 20 rated facilities so a handful of homes can't swing the mean. The worst-rated table is limited to 1-star facilities with 60 or more certified beds, ranked by bed count, to surface the largest low-rated providers rather than tiny outliers. CMS ratings lag real conditions by several months and roll up to the facility, not the specific unit — use them alongside an in-person visit.
