The numbers are contained in wealth intelligence firm New World Wealth’s latest Africa Wealth Report, the continent’s most comprehensive assessment of incomes at country, city and individual level. Researchers analyse household income statistics, market capitalisation data, detailed records of high-net-worth individuals from the firms’ in-house database, property sector information, tax data and other tools, to support their findings.

The research is combined in a model that estimates both the total wealth held in a country and the number of individuals in each wealth tier. Estimates of the top wealth tiers, namely, centi-millionaires and billionaires, are produced from the firms’ in-house database of high-net-worth individuals.
