In 2014, after implementation of the Health Insurance Marketplaces and Medicaid expansion created through the Affordable Care Act (ACA), 36 million people in the United States—11.5% of the population—were uninsured, according to the CDC’s National Center for Health Statistics.
About two-thirds of the US population (63.6%) younger than 65 years had private health insurance last year, including 2.2% covered by plans purchased through health insurance exchanges. The largest drop in uninsured adults occurred among 19- to 25-year-olds, from 26.5% in 2013 to 20% in 2014. This group also had the biggest increase in public coverage, rising to 19.1% in 2014 from 16.1% in 2013.
