How about that. The Associated Press covers the release of new census information showing that by 2050, 1 in 6 people will be older adults:
"The world's population has been graying for many years due to declining births and medical advances that have extended life spans. As the fastest-growing age group, seniors now comprise just under 8 percent of the world's 6.8 billion people. But demographers warn the biggest shift is yet to come. They cite a coming wave of retirements from baby boomers and China's Red Guard generation that will shrink pensions and add to rising health care costs.
Germany, Italy, Japan and Monaco have the most senior citizens, with 20 percent or more of their people 65 and older."
The piece also talks about the health care crisis and how these estimates should be a factor when dealing with health care reform. Check it out.
