The average age of the world's population is increasing at an unprecedented rate. The number of people worldwide age 65 and older is estimated at 506 million as of midyear 2008; by 2040, that number will hit 1.3 billion. Thus, in just over 30 years, the proportion of older people will double from 7 percent to 14 percent of the total world population, according to a new report, "An Aging World: 2008."
The report examines the demographic and socioeconomic trends accompanying this phenomenon. It was commissioned by the National Institute on Aging (NIA), part of the National Institutes of Health, and produced by the U.S. Census Bureau. It was released today by the Census Bureau.
"The world's population of people over age 65 is growing rapidly, and with it will come a number of challenges and opportunities," said NIA Director Richard J. Hodes, M.D. "NIA and our partners at Census are committed to providing the best data possible so that we can better understand the course of population aging and its implications."
