Healthy Aging: Preventing Disease and Improving Quality of Life Among Older Americans, 2004

摘要

One hundred years ago, only 3 million people in this country were over the age of 65. Today, more than 33 million Americans are in this age group, and that number is expected to double over the next 30 years, as baby boomers age. The seniors of the 2030s will be even more racially and ethnically diverse than today's seniors. The aging of America will trigger a huge demand for health care and social services. Health care expenditures for a 65-year-old are now four times those for a 40-yearold. Because the population will be older and greater in number, overall U.S. health care expenditures are projected to increase 25% by 2030.
