Primarily due to the Affordable Care Act, the United States has made great progress in expanding health insurance coverage. The uninsured rate is at an historic low of 7.7 percent. In 2010, it was 16 percent before the ACA’s enactment.

According to federal reports, 45 million people are covered by the ACA, with 24 million through the Health Insurance Marketplace and the remainder through Medicaid expansion for those who previously did not qualify. The ACA financially enables states to expand their Medicaid programs by providing a federal match that covers 90 percent of the expansion costs.
