title: Changing demographics of the American population.
abstract: Since 1950, the United States has been in the midst of a profound demographic change: the rapid aging of the population. The baby boom generation began turning 65 in 2011 and is now driving growth at the older ages of the population. This article highlights geriatric demographic changes and illustrates how these and future trends will have wide ranging implications for the US health care system.
