World not prepared to support growing elderly population, report by UN, aged care group finds --- The world is aging so fast that most countries are not prepared to support their swelling numbers of elderly people, according to a global study being issued Tuesday by the United Nations and an elder rights group. --- The report ranks the social and economic well-being of elders in 91 countries, with Sweden coming out on top and Afghanistan at the bottom. It reflects what advocates for the old have been warning, with increasing urgency, for years: Nations are simply not working quickly enough to cope with a population graying faster than ever before. By the year 2050, for the first time in history, seniors older than 60 will outnumber children younger than 15. - Associated Press
