The Union County medicare advantage market
About 51% of Union County's 2,542 Medicare beneficiaries are in Medicare Advantage — right around the national norm — so you'll find a genuine mix of competitive MA plans and Medigap options here rather than a one-sided market. Humana currently leads the county by enrollment, but the lowest total-cost plan for your specific drugs and doctors is often a smaller carrier — which is why we run all of them side by side instead of pushing the biggest name. Right now roughly 8 Medicare Advantage plans are available in Union County, so a side-by-side comparison genuinely matters. Medicare Advantage enrollment figures reflect the latest CMS data (May 2026).

What makes Union County different: Union County is Florida's smallest county by land area (about 250 square miles) and its economy is dominated by the state prison system: the Union Correctional Institution (Florida's oldest and largest correctional institution, established 1913) and the adjoining Reception and Medical Center put roughly 4,774 people in group quarters - about a third of all residents - and make the Florida Department of Corrections and other government the county's largest employer. This produces a roughly 63.8% male / 36.2% female population split (about 176 males per 100 females) that suppresses the county's apparent senior share and concentrates much of its Medicare base in dual-eligible and under-65 disability beneficiaries. (Note: Florida's least-populous county is Liberty County, not Union.)
