This project developed a calculator to help people anticipate how a change in earnings from employment would affect their net income, and in so doing, provide public benefit recipients with their estimated effective marginal tax rate on new earnings. Key Points:

Understanding Coverage Considerations for COVID-19 Vaccines and Treatments (Updated May 2023)

This Issue Brief presents current estimates of enrollment in health insurance coverage obtained through the Affordable Care Act (ACA) Marketplaces, Medicaid expansion, Children's Health Insurance Program, Basic Health Program and the subsequent reductions in state-level uninsured rates since the ACA was implemented in 2014.

This Issue Brief examines children’s health coverage trends using the National Health Interview Survey from 2010 through the third quarter of 2022 and reviews recent research findings from the National Survey of Children's Health on children’s access to and utilization of health care services during this period, including the COVID-19 pandemic.

This report provides current HHS projections of the number of individuals predicted to lose Medicaid coverage at the end of the COVID-19 public health emergency (PHE) due to a change in eligibility or due to administrative churning.

This report highlights the impacts of the Affordable Care Act's Marketplace subsidies on coverage rates among self-employed adults and small business owners, based on tax data from the Department of Treasury and national survey data.

This report examines recently-released 2021 National Health Interview Survey data to assess coverage changes during the pandemic, finding a decrease in the uninsured rate in 2021 for the population as a whole and by race, ethnicity, and income.

In response to the COVID-19 Public Health Emergency, the Centers for Medicare & Medicaid Services provided a 2021 Special Enrollment Period (SEP) from February 15 to August 15, 2021. Understanding the sociodemographic composition of Marketplace enrollees allows for better targeted outreach and enrollment assistance. However, many enrollees do not report their race and ethnicity.

The American Rescue Plan (ARP) includes two key provisions that expand and increase premium tax credit benefits for Marketplace consumers, improving affordability of coverage for millions. Under current law, these provisions will sunset in 2023 if they are not extended, resulting in higher out-of-pocket costs for enrollees and an increase in the number of uninsured.

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.
