US life expectancy at age 50 falling behind rest of developed world

Since the 1970s, life expectancy for women and men in the United States has continued to improve, but the US has fallen behind most other wealthy countries. This graph shows life-expectancy at age 50 for women in 10 countries. At NIA’s request, a committee of the National Academy of Sciences investigated the reasons for this poor performance in health at older ages, and NIA has funded several projects designed to elucidate reasons and possible remedies. The final report from the NAS Panel is available here, and a Program Announcement relating to this topic is available on the BSR page. Details of a previous RFA on International Differences in Health, Longevity, and SES are also available.
