The Affordable Care Act and Its Accomplishments

Publication Date

The Affordable Care Act (ACA) was signed into law on March 23, 2010. Since then, the law has led to an historic expansion of health insurance coverage across all states and all demographic groups within the U.S. This Briefing Book features key findings from two dozen reports published in 2021-2022. Most of the reports were published by the Office of the Assistant Secretary and Planning and Evaluation (ASPE) in the Department of Health and Human Services (HHS), working in collaboration with the Centers for Medicare & Medicaid Services (CMS), which is primarily responsible for the implementation of many of the ACA’s provisions and also releases regular Medicaid and Marketplace enrollment reports. The Briefing Book also includes a report by the White House Council of Economic Advisors. The Briefing Book summarizes key findings in five areas:

  • Health Coverage and Uninsured Rates
  • Marketplace Coverage
  • Medicaid
  • Preventive Care
  • Populations of Interest
