From this week’s Economist…

Russia’s population is expected to fall by 22% between 2005 and 2050, Ukraine’s by a staggering 43%. Now the phenomenon is creeping into the rich world: Japan has started to shrink and others, such as Italy and Germany, will soon follow. Even China’s population will be declining by the early 2030s, according to the UN, which projects that by 2050 populations will be lower than they are today in 50 countries.
