The world's combined working-age population will grow by 26 percent by 2050, but in Korea and Japan it will shrink by about the same margin, the UN predicts.
The UN in a global report forecast that the combined population between ages 15 and 64 in advanced economies will start to shrink from next year, falling five percent by 2050.
Japan will see the largest drop of 28 percent, followed by Korea's 26 percent, and Germany's and Italy's 23 percent.
But the working-age population in the U.S. will increase by 10 percent thanks to a growing fertility rate and open immigration policies, the UN claims, though its proportion of the total population will drop from 66 percent to 60 percent.
Among emerging economies, India's working-age population is expected to rise by 33 percent and Brazil's three percent. But there will be a 21-percent drop in Russia and China.
The UN predicts that Japan's population will have decreased by 2050, bringing down the ratio of the working population and dependent non-working population to 10:9.5. Currently, 10 working-age people support 6.4 dependent people in Japan.
China is expected to see the dependency ratio to rise from 3.7 per 10 working-age people in 2015 to seven in 2050, but the situation is as worrisome as in Japan because it is aging faster and is less wealthy.
