"Today’s older Americans enjoy longer lives and better physical function than did previous generations, although, for some, an increased burden in housing costs and rising obesity may compromise these gains, according to a comprehensive federal look at aging. The report, Older Americans 2012: Key Indicators of Well-Being, tracks trends at regular intervals to see how older people are faring as the U.S. population grows older. In 2010, 40 million people age 65 and over accounted for 13 percent of the total population in the United States. In 2030, the number and proportion of older Americans is expected to grow significantly—to 72 million, representing nearly 20 percent of the population said the report, by the Federal Interagency Forum on Aging-Related Statistics. This report provides the latest data on the 37 key indicators selected by the Forum to portray aspects of the lives of older Americans and their families. It is divided into five subject areas: population, economics, health status, health risks and behaviors, and health care."
