Where New Jersey sits among the states
40.9% of everyone with Medicare in New Jersey is in a Medicare Advantage or other health plan rather than Original Medicare. That puts New Jersey 36th of 51, between Oklahoma above it and Virginia 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.
