Estimated number of uninsured without ACA in the U.S. 2015-2025

ACA: Affordable Care Act
Figures reflect average enrollment over the course of a year and include spouses and dependents covered under family policies; people reporting multiple sources of coverage are assigned a primary source.
The uninsured population includes people who will be unauthorized immigrants and thus ineligible either for exchange subsidies or for most Medicaid benefits; people who will be ineligible for Medicaid because they live in a state that has chosen not to expand coverage; people who will be eligible for Medicaid but will choose not to enroll; and people who will not purchase insurance to which they have access through an employer, through an exchange, or directly from an insurer.
