This report explains how the ACA expands coverage nationally, including a breakdown of how many uninsured people are eligible for Medicaid, how many are eligible for financial assistance to help them buy private insurance in the new Marketplace and how many will not receive any financial assistance at all. The report also details, in specific dollar figures, the income levels at which people are eligible for Medicaid or financial assistance in the Marketplace. For states not expanding Medicaid, the report quantifies how many uninsured people fall into the “coverage gap,” meaning they will be ineligible for financial assistance in the Marketplace or for Medicaid in their state despite having an income below the federal poverty level.
