Iowa: *Final* avg. 2020 #ACA premiums: 10.8% decrease
When I ran the numbers for Iowa's preliminary avg. 2020 unsubsidized individual market rate changes, I had to use an unweighted average reduction of around 3.3%. However, knowing the relative market share of each carrier can make a big difference.
Case in point: It turns out that Medica holds something like 97% of Iowa's ACA-compliant market...whcih means the 11.3% rate drop by Medica heavily weighs the overall average. Wellmark is raising their rates by about 4.7%, but that only nudges the statewide weighted average to a 10.8% reduction overall.
