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.

Combined, that's 306,000 people, although assuming the national average 6.6% net enrollment attrition rate applies, current enrollment would be back down to more like 286,000 statewide.

How did we get here?

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

Combined, that's 5.3% of their total population.

Assuming the national average 6.6% net enrollment attrition rate thru April reported by the Centers for Medicare & Medicaid Services applies to Indiana, however, that would knock the current enrollment down to more like 341,000 statewide.

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.

The Centers for Medicare & Medicaid Services (CMS) has posted an official update to the enrollment data for ACA Medicaid expansion through December 2024.

I've been able to cobble together more recent ACA expansion enrollment for about half of the 40 states (+DC) which participate in the program:
