Where Connecticut sits among the states
57.2% of everyone with Medicare in Connecticut is in a Medicare Advantage or other health plan rather than Original Medicare. That puts Connecticut 7th of 51, between Wisconsin above it and North Carolina 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.
