Also, the world’s youngest region is sub-Saharan Africa where 41 per cent of the population is aged 15 or younger.
“The oldest populations are found in Monaco (Italy), where the share of the population aged 65 and older is 36 per cent; Japan, with 29 per cent of its population aged 65 and older; and Southern Europe – the oldest region in the world, with 22 per cent of its population is aged 65 and older.
