Globally those over the age of 60 are more than 800 million (12 percent of the world population) and this is growing, with the expectation that it will reach more than two billion by 2050 (21 percent of the population). Currently 70 percent of the world’s older population live in developed and developing countries, but by 2025, 80 percent of the older population will be living in less developed countries. Older persons are projected to exceed the number of children by 2047. It has already started in developed countries. In 2015, Japan became the first country in the world where more adult than baby diapers were sold.
