The Brazoria County medicare supplement market
About 58% of Brazoria County's 65,560 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. Only 13% of Brazoria residents are 65 or older, so it's a younger county where fewer agents specialize in Medicare locally — exactly the gap a dedicated Texas agent fills. UnitedHealthcare 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 32 Medicare Advantage plans are available in Brazoria County, so a side-by-side comparison genuinely matters. Medicare Advantage enrollment figures reflect the latest CMS data (May 2026).

What makes Brazoria County different: Brazoria County straddles the Houston petrochemical corridor and the Gulf Coast: the Dow Chemical Texas Operations complex at Freeport is one of the largest chemical manufacturing sites in the Western Hemisphere, anchoring a working-age, blue-collar economy. The county's 65+ share (13.4%) sits below the Texas average, while fast-growing Pearland in the north functions as a Houston suburb served by Memorial Hermann Pearland and HCA Houston Healthcare Pearland.
