New Hampshire: Medicaid expansion enrollment up 43% since COVID struck; total Medicaid up 21%

New Hampshire

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

Today I'm presenting New Hampshire

For enrollment data from January 2021 on, I'm relying on adjusted estimates based on raw data from the New Hampshire Dept. of Health & Human Services.

Aside from a strange 6-month "bump" in enrollment in late 2016/early 2017, New Hampshire's overall Medicaid enrollment has hovered in the ~180,000 range for years...until the COVID pandemic hit last February. Since then, traditional Medicaid enrollment has gone up a modest 12%, but ACA expansion enrollment increased by 42.6% for an overall 21.1% hike.

New Hampshire has 1,377,529 residents according to the 2020 U.S. Census. As of April 2021:

  • around 220,000 were enrolled in Medicaid overall, or around 16% of the population
  • around 143,000 were enrolled in non-ACA Medicaid
  • around 77,000 were enrolled in ACA Medicaid expansion.
  • Add in the ~31,000 subsidized ACA exchange enrollees and that's around 108,000 New Hampshire residents who would lose healthcare coverage if the Supreme Court strikes down the Affordable Care Act, or 7.8% of the state population.
