  • ACA Coverage Expansions and Low-Income Workers

    Issue Brief

    This brief highlights low-income workers and the impact of ACA coverage expansions on this population.

Medicaid plays an important role in providing health coverage for low-income workers, and coverage expansions implemented under the ACA have produced substantial coverage gains for low-income workers and a corresponding reduction in the uninsured. However, low-income workers in non-expansion states with incomes too high for Medicaid but too low for subsidies in the Marketplace do not have an affordable coverage option and will likely remain uninsured.
