Minnesota has around 151,000 residents enrolled in ACA exchange plans, 61% of whom are currently subsidized. I estimate they also have another ~62,000 unsubsidized off-exchange enrollees.
Kansas has around 200,000 residents enrolled in ACA exchange plans, 94% of whom are currently subsidized. I estimate they also have another ~6,000 unsubsidized off-exchange enrollees.
Kentucky has around 97,000 residents enrolled in ACA exchange plans, 86% of whom are currently subsidized. I estimate they also have another ~6,800 unsubsidized off-exchange enrollees.
Indiana has around 359,000 residents enrolled in ACA exchange plans, 90% of whom are currently subsidized. I estimate they also have another ~6,700 unsubsidized off-exchange enrollees
Iowa has around 136,000 residents enrolled in ACA exchange plans, 88% of whom are currently subsidized. I estimate they also have another ~9,600 unsubsidized off-exchange enrollees.
Hawaii has around 26,000 residents enrolled in ACA exchange plans, 83% of whom are currently subsidized. I estimate they also have perhaps another ~1,700 unsubsidized off-exchange enrollees.
Idaho has around 117,000 residents enrolled in ACA exchange plans, 86% of whom are currently subsidized. I estimate they also have another ~9,000 unsubsidized off-exchange enrollees, although the actual rate filings (summarized later in this post) put the off-exchange total at a much higher ~47,000.
Combined, that's 6.2 - 8.0% of their total population.
Alabama has around 477,000 residents enrolled in ACA exchange plans, 96% of whom are currently subsidized. I estimate they also have perhaps another ~33,000 unsubsidized off-exchange enrollees.
Wyoming has ~46,000 residents enrolled in ACA exchange plans, 95% of whom are currently subsidized. They also have an unknown number of off-exchange enrollees (likely only a few thousand at most). Combined, that's around 8% of their total population.
(Note, however, that the official actuarial rate filings for the 3 carriers offering coverage in the Wyoming individual market only report a combined total of around 39,000 enrollees as of spring 2025, or 6.6% of the total population).
Alaska has around ~28,000 residents enrolled in ACA exchange plans, 88% of whom are currently subsidized. They also have an unknown number of off-exchange enrollees in ACA-compliant individual market policies. Overall, including net attrition, I estimate their total enrollment both on & off exchange to be perhaps ~27,000 or so.
