Health Affairs reports that U.S. Census Bureau figures indicate that after full implementation of the ACA in 2014 and the expansion of insurance coverage that followed, there was a sharp drop in the number of uninsured Americans. That level has now stabilized, with the percentage of uninsured for the entire year dropping from 9.1 percent (29 million) in 2015 to 8.8 percent (28.1 million) in 2016.

Coverage changed only marginally for most forms of insurance, with the only statistically significant gain in coverage (0.4 percent) occurring in the Medicare population.

Modern Healthcare reports that job-based insurance is still the most common source of coverage, with 55.7 percent of people finding insurance that way. Medicaid accounts for 19.4 percent, while Medicare takes care of 16.7 percent. When it comes to buying insurance directly from a health plan or through an exchange, 16.2 percent receive coverage that way; 4.6 percent have military-based coverage.
