Tanzania

Tanzania leads Africa in population growth with an annual rate of 3.0%, outpacing #6 South Africa’s 0.6% by a factor of five. Its 68.1 million people drive one of the continent’s fastest urbanization rates, as cities like Dar es Salaam expand at 5.6% annually. This demographic surge supports a dual economy where tourism generates $2.5 billion yearly and agriculture employs 65% of the workforce. Yet the rapid growth strains infrastructure, making it a land of opportunity and challenge — cheaper land than in #7 Kenya attracts foreign investors, but housing supply trails demand by 40%.
