About The Study: An estimated 3 of 4 U.S. children relied on publicly subsidized insurance (Medicaid, Children’s Health Insurance Program [CHIP], or Marketplace) or experienced a period without any insurance by their 18th birthday in the post-Affordable Care Act (ACA), pre-pandemic policy environment. Substantial state heterogeneity in childhood un-insurance underscores the critical role of Medicaid policies.
