The Growing Cost of Aging in America

As baby boomers age, the sheer number of older adults will be unprecedented in U.S. history. The portion of the population living on fixed incomes with high medical expenses will increase as the proportion of seniors — especially those older than 85 — grows. As a result, the health care system and federal programs such as Medicare and Social Security will come under increasing financial strain.

In 2015, there were already 47.8 million people aged 65 and older in the United States.1
