Nigeria records a steep decline in private wealth over the past decade while retaining its ranking among African countries by the number of dollar millionaires, according to the 2025 Africa Wealth Report by Henley & Partners in collaboration with New World Wealth. The report says Nigeria has an estimated 7,200 dollar millionaires, 20 “centi-millionaires” (at least $100 million) and three billionaires, placing it fourth in Africa by millionaire population. Despite this position, Nigeria experiences one of the sharpest decreases in high-net-worth individuals on the continent, with its millionaire population down 47% compared with 2015, according to the sources. In the overall African ranking, South Africa leads with 41,100 millionaires, followed by Egypt with 14,800 millionaires. Morocco ranks third with 7,500 millionaires, narrowly ahead of Nigeria, while Kenya completes the top five with 6,800 millionaires. The report also notes that some countries are excluded from comparisons due to insufficient reliable data, including Tunisia and the Democratic Republic of Congo.
