Where Delaware sits among the states
32.7% of everyone with Medicare in Delaware is in a Medicare Advantage or other health plan rather than Original Medicare. That puts Delaware 46th of 51, between Kansas above it and Vermont below. Across the country the same figure runs from 62.8% in Michigan down to 3.0% in Alaska, so what counts as the ordinary choice depends on where a person lives, and this is what it is where they do.
