The 54,980 residents now between 60 and 64 will become Medicare-eligible soon, and our turning 65 guide walks through it. Census 2023 estimates show 64% of the 65-plus population is under 75, 28% is 75 to 84 and 8% is 85 or older. CMS data show 57.3% of Gwinnett County residents with Medicare chose Medicare Advantage, which is close to the 56.2% average across Georgia. A county average does not tell you which kind of plan fits you. Whether Medicare Advantage or Original Medicare with a Medigap plan is the better fit depends on your doctors, your prescriptions and how you want to handle costs, so we compare both for your ZIP code.
