As fivethirtyeight.com documented earlier this week, in spite of Obamacare’s extensions of health care coverage to millions of previously uninsured Americans, 33 million still don’t have coverage. Who are those people and why aren’t they covered? Some are noncitizen immigrants; others fall into the “Medicaid gap” (referring to the range of “incomes that were too high for Medicaid eligibility and too low to receive subsidies on the new health care exchanges”); yet others are young adults ("young invincibles") who have historically been difficult to convince to sign up. Aside from those categories, 14.4 million people remain uninsured. Why?
Fivethirtyeight has some ideas (about this question and all of these categories of uninsured), here. The bottom line is that we’re still far from achieving universal coverage.
