America's older population

摘要

Older Americans have increased steadily in number and proportion of the total U.S. population. The population age 65 and older numbered 35 million in 2000 and is expected to more than double by 2050. The older population was 12 percent of the totalpopulation in 2000 and will increase to 20 percent by 2050. Moreover, the oldest segment of the older population, those age 85 and older, has been increasing more rapidly than any other age group. As America enters the 21st century, its older populationis living longer, is better educated, and is more prosperous than previous generations. Despite these advances, disparities among the older population persist between men and women, racial and ethnic groups, and income classes. With the leading edge of the baby boom generation reaching age 65 in 2011, growth of the older population will increase more rapidly. In light of the rapid growth of the older population over the next 50 years, there is an urgent need for policymakers, researchers, and communityleaders to better understand the health and economic needs of this segment of American society.
