Ten states have uninsured rates below 5 percent. What are they doing right?
Universal health care remains an unrealized dream for the United States. But in some parts of the country, the dream has drawn closer to a reality in the 13 years since the Affordable Care Act passed.
Overall, the number of uninsured Americans has fallen from 46.5 million in 2010, the year President Barack Obama signed his signature health care law, to about 26 million today. The US health system still has plenty of flaws — beyond the 8 percent of the population who are uninsured, far higher than in peer countries, many of the people who technically have health insurance still find it difficult to cover their share of their medical bills. Nevertheless, more people enjoy some financial protection against health care expenses than in any previous period in US history.
