Same-ownership peers

Where these figures come from
The figures above come directly from the U.S. Centers for Medicare \& Medicaid Services Nursing Home Compare dataset for federal quality ratings, combined with the CareScout 2025 Cost of Care Survey of more than 15,000 elder-care providers nationwide and U.S. Census American Community Survey income data. Cost figures are monthly medians, refreshed annually with each new CareScout release; quality ratings are refreshed quarterly from the CMS Provider Information File. Read these state and county medians as benchmarks, then verify current rates with individual providers and consult care managers before making placement decisions.
