Health insurance coverage in the United States is provided by several public and private sources. During 2019, the U.S. population overall was approximately 330 million, with 59 million people 65 years of age and over covered by the federal Medicare program. The 273 million non-institutionalized persons under age 65 either obtained their coverage from employer-based (159 million) or non-employer based (84 million) sources, or were uninsured (30 million). During the year 2019, 89% of the non-institutionalized population had health insurance coverage. Separately, approximately 12 million military personnel (considered part of the "institutional" population) received coverage through the Veteran's Administration and Military Health System.
