Kenya

Kenya holds seventh place at 53.3 million, powered by a birth rate of 3.3 children per woman — higher than #8 Sudan’s 3.0. The tech hub Nairobi drives youth migration, with 75% of the population under 35, fueling a $1 billion tech sector that grows 10% annually. This digital ecosystem is 30% faster than the Ethiopian average in startup formation, though urbanization strains water supplies where 40% of Nairobi lacks consistent access. Kenya’s mix of demographic youth and digital innovation keeps it firmly in the top ten.
