Why State Medicare Data Matters
Medicare looks different in every state. Medicare Advantage penetration ranges widely — in some states more than half of beneficiaries choose a Medicare Advantage plan, while in others most stay on Original Medicare and pair it with a Medicare Supplement (Medigap) plan. Those choices are shaped by how many plans are offered locally, the strength of regional hospital networks, and average Medigap premiums in the state.
Understanding the landscape where you live helps you ask better questions. If Advantage plans are common in your county, it usually means more $0-premium options and richer extra benefits — but also network restrictions to check. If most of your neighbors stay on Original Medicare, robust Medigap competition may make a Supplement more affordable. Either way, county-level enrollment tells you how much choice you really have.
Use the figures above as a starting point, then compare your specific options with our plan comparison tool or read the Medicare Advantage vs. Supplement guide. When you want personalized help, a licensed advisor can review the plans available at your exact address — at no cost.
