According to a National Research Council report, Explaining Divergent Levels of Longevity in High-Income Countries, life expectancy in the United States continues to increase, but at a slower rate than in the past. The most likely culprits are smoking and obesity; the latter may account from 1/5 to 1/3 of the reduced rate. According to the CIA World Factbook, the United States currently ranks 49th in the world in life expectancy. (Monaco, at nearly 90, is first.)
