Enrollment and county data: Centers for Medicare & Medicaid Services, Medicare Monthly Enrollment, 2024 (data.cms.gov). Figures are 2024 annual counts. Medicare Advantage percentage = (beneficiaries in Medicare Advantage & Other Health Plans ÷ total beneficiaries) × 100. The county table shows the 15 most-populous counties of 159 total.
Part B premium: CMS, 2026 Medicare Parts A & B Premiums and Deductibles. The standard premium is set federally and is the same in every state; higher-income beneficiaries pay an income-related adjustment (IRMAA).
Plan counts and Medigap: KFF, Medicare Advantage 2026 Spotlight (CMS Landscape files); AHIP, The State of Medicare Supplement Coverage, 2023. These are reported as national figures only.
Limitations: Medicare Supplement (Medigap) enrollment and per-county plan counts are not available in an open dataset at the state or county level, so they are not shown per county. Percentages are rounded. Last updated 2026-06-11.
