Nebraska has around ~136,000 residents enrolled in ACA exchange plans, 95% of whom are currently subsidized. I estimate they also have another ~2,000 unsubsidized off-exchange enrollees.
Pennsylvania has around ~496,000 residents enrolled in ACA exchange plans, 87% of whom are currently subsidized. I estimate they also have another ~103,000 unsubsidized off-exchange enrollees.
New Hampshire has around ~70,000 residents enrolled in ACA exchange plans, 71% of whom are currently subsidized. I estimate they also have another ~14,000 unsubsidized off-exchange enrollees.
New York has around ~222,000 residents enrolled in ACA exchange plans, 63% of whom are currently subsidized. I estimate they also have another ~31,000 unsubsidized off-exchange enrollees.
North Carolina has around ~975,000 residents enrolled in ACA exchange plans, 94% of whom are currently subsidized. I estimate they also have another ~37,000 unsubsidized off-exchange enrollees.
Mississippi has around ~338,000 residents enrolled in ACA exchange plans, 98% of whom are currently subsidized. I estimate they also have another ~14,000 unsubsidized off-exchange enrollees.
The District of Columbia has around ~15,000 residents enrolled in ACA exchange plans. Unlike most states where nearly all ACA exchange enrollees are subsidized, in DC only around 28% are due to the District having an unusually high income eligibility threshold for Medicaid (210%).
DC also has a unique requirement that ACA individual market plans can only be sold on their ACA exchange; I'm assuming perhaps 1,000 off-exchange enrollees regardless but officially I believe this should be pretty much zilch. With net attrition since January, however, it looks like the grand total is actually a bit below 14,000 District-wide.
Montana has around ~77,000 residents enrolled in ACA exchange plans, 89% of whom are currently subsidized. I estimate they also have another ~8,400 unsubsidized off-exchange enrollees.
Missouri has around ~417,000 residents enrolled in ACA exchange plans, 94% of whom are currently subsidized. I estimate they also have another ~3,600 unsubsidized off-exchange enrollees.
Louisiana has around ~293,000 residents enrolled in ACA exchange plans, 96% of whom are currently subsidized. I estimate they also have another ~13,000 unsubsidized off-exchange enrollees.
