Ohio: Medicaid expansion enrollment reaches 588,000; total Medicaid up 13.5% since COVID hit

I've once again relaunched my project from last fall to track Medicaid enrollment (both standard and expansion alike) on a monthly basis for every state dating back to the ACA being signed into law.

For the various enrollment data, I'm using data from Medicaid.gov's Medicaid Enrollment Data Collected Through MBES reports. Unfortunately, they've only published enrollment data through December 2020. In most states I've been able to get more recent enrollment data from state websites and other sources.

For Ohio, I'm relying on raw data from the Ohio Dept. of Medicaid for January 2021 and later.

Total Medicaid enrollment in Ohio peaked in January 2016 at nearly 3.2 million enrollees before gradually sliding down to roughly 2.75 million just before the COVID pandemic hit. Since then its reversed course, with non-expansion enrollment increasing 16.6% and the ACA expansion population going up slightly (1.7%), for an overall increase of 13.5% statewide.

Ohio has 11,799,448 residents according to the 2020 U.S. Census. As of April 2021:

• around 3.13 million were enrolled in Medicaid overall, or 26.5% of the population
• around 2.54 million were enrolled in non-ACA Medicaid
• around 588,000 were enrolled in ACA Medicaid expansion

Add in the ~163,000 subsidized ACA exchange enrollees and that's around 751,000 Ohio residents who would lose healthcare coverage if the Supreme Court strikes down the Affordable Care Act, or 6.4% of the state population.
