Global Rankings, Data Sources, and Methodology
Forbes and Bloomberg compile family wealth rankings using a combination of public company filings, stock market data, private company valuations, and interviews with family representatives. The methodology accounts for family members’ direct and indirect shareholdings, trusts, and foundations, while excluding personal debts where possible. Forbes billionaires methodology explains how net worth estimates are calculated and updated periodically. SEC filings and annual reports from publicly traded companies provide audited financial data used to verify family stakes in listed firms.
Wealth rankings can shift quickly due to stock market movements, currency fluctuations, and changes in private company valuations. Families with diversified holdings across multiple sectors tend to show more stability in rankings compared to those concentrated in a single industry. SEC EDGAR filings offer transparency on public company ownership and insider transactions. The latest available public data continues to place the Walton, Mars, Koch, Hermès, and Saudi royal families among the most prominent entries in global wealth lists.
