Over 21.4 million Americans selected or were automatically re-enrolled in 2024 Marketplace coverage, the Centers for Medicare & Medicaid Services reported March 22, up slightly from the 21.3 million reported in January. The total includes 5.2 million first-time enrollees. People receiving advance premium tax credits saved an average 48% on monthly premiums, with nearly 9.4 million selecting a plan for $10 or less per month.

According to a new Department of Health and Human Services report, 45 million people are currently enrolled in Marketplace or Medicaid expansion coverage under the Affordable Care Act, the highest total on record. HHS also released an update on enrollment trends since the launch of the ACA Health Insurance Marketplaces in 2014, including a report on enrollment by race and ethnicity.
