Despite tight budgets, nearly all states maintained or made targeted expansions or improvements in their Medicaid and Children’s Health Insurance Programs (CHIP) eligibility and enrollment rules in 2010, preserving the programs’ important role of providing coverage to millions of low-income Americans who otherwise lack affordable options.

Section 1115 Medicaid demonstration waivers offer states an avenue to test new approaches in Medicaid that differ from what is required by federal statute, so long as the approach is likely to “promote the objectives of the Medicaid program.” Waivers generally reflect priorities identified by states as well as changing priorities from one presidential administration to another. The Biden administration encouraged states to propose waivers that expand coverage, reduce health disparities, advance whole-person care, and improve access to behavioral health care. Looking ahead, the new Trump administration’s waiver priorities will likely differ significantly from those of the Biden administration. However, it is unclear how the Trump administration will treat certain waivers promoted and approved by the Biden administration.

Economic conditions, federal and state policy decisions, and major health crises like the COVID-19 pandemic influence the uninsured rate. While implementation of the Affordable Care Act, namely the expansion of Medicaid and availability of subsidized Marketplace coverage, led to a drop in the share of people who are uninsured, disparities in coverage persist and policy changes in the 2025 budget reconciliation bill are expected to increase the size of the population.
While climate change poses health threats for everyone, people of color, low-income people, and other marginalized or high-need groups face disproportionate risks due to underlying inequities and structural racism and discrimination.
The surge in COVID-19 cases triggered by the omicron variant led to widespread work disruptions, with about 4 in 10 workers (42%) – including 6 in 10 of those with lower incomes – saying they had to miss work at least once in the past three months because of a COVID-19 illness, quarantine, or closure,…
