The main objective of the Affordable Care Act (ACA) was to increase enrollment in health insurance among those who were previously uninsured. Official estimates from the Census Bureau have consistently overstated the number of people who are uninsured. A major factor in the overestimate is the undercount of people in Medicaid. Also, millions of Americans have been officially uninsured despite their eligibility for public insurance or employer coverage. With the passage of the ACA, fewer than 10 percent of the remaining uninsured do not have a realistic path to securing health insurance. The future of the ACA is now uncertain, but any future policy changes will likely need to provide a sure path to insurance coverage for all Americans as well.
