Pennsylvania didn't launch ACA expansion until 2015. Once it ramped up, total enrollment (both ACA & non-ACA) hovered around the 2.8 - 2.9 million range until COVID hit. Since then, non-ACA Medicaid has gone up by 9.8%; the expansion population has grown by 29.8%; and overall enrollment is up 15.2%.
Total Medicaid enrollment in Oregon (including ACA expansion peaked at a little over 1.1 million back in 2015, but dropped off to around 950,000 for a couple of years before COVID hit the country. Since then, non-ACA enrollment has gone up about 14%, ACA expansion has increased by over 30% and overall enrollment is 22% higher than it was in February 2020.
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. Unfortunately, I've been unable to do so for North Dakota, so the data below is still six months out of date.
Total Medicaid enrollment in North Dakota stayed fairly steady from 2016 - early 2020...but after the COVID pandemic hit, it jumped significantly, with non-ACA enrollment increasing 21.4%, ACA expansion going up 18.3% and total enrollment increasing by 20.7% overall.
