, the developing economies showed the opposite balance. Nigeria had the youngest profile because approximately 42 per cent of every hundred residents were below 15, and only 3 per cent had reached 65. India and Morocco occupied a middle position, with around 25 and 26 in the junior group and 7 and 8 in the senior category, which reflected their rapidly growing cities. Brazil, meanwhile, was the most balanced, registering 20 and 10.
