Already now, 23% of Japan’s population is over 65, and 6% is over 80. By the year 2050 those numbers are projected to be nearly 40% and 16%, respectively. (The corresponding numbers for the African country of Mali are only 3% and 0.1%.) At that point, Japanese people over the age of 80 will outnumber kids under 14, and people over 65 will outnumber those kids by more than 3 to 1.
