China's Population Decline

Read the following in a a review of Josef Joffe's new book, The Myth of America’s Decline: Politics, Economics, and a Half Century of False Prophesies:

“China’s working-age population will reach its peak at the end of this decade and decades before the People’s Republic is supposed to overtake the United States.” Meanwhile, thanks to our fertility rates and immigration, the U.S. will have a population of younger workers. It has not escaped the attention of observers that, by 2025, China would account for less than a fifth of the world’s population, but almost a fourth of the world’s senior citizens.”
