Few children in industrialised nations
In Germany, only 13.1% of the population were aged under 15 years in 2013. In a worldwide comparison, children and juveniles had a similarly small share in the population only in Japan, where the rate was also 13.1%, according to the World Bank. The process of demographic ageing can now be observed not only in nearly all European countries, but also in other large industrialised nations such as the Russian Federation or Canada.
The youngest population worldwide was recorded in the African countries south of the Sahara. In Niger, one in two inhabitants (50%) were under 15 years old in 2013. This was true of 48% of the population in Chad, Angola and Uganda.
