20 Richest Women in the U.S.: Forbes, 2023

On Tuesday, Forbes released its flagship Forbes 400 list of America's wealthiest people, which includes the richest women in the U.S. When possible, researchers met with listees in person or spoke with them virtually or by phone, and interviewed their employees, handlers, asset managers and financial advisors, rivals, peers and attorneys. They also pored over Securities and Exchange Commission documents, court filings, probate records and news articles. They took into account all types of assets, and factored in debt and charitable giving. To see how philanthropic each Forbes 400 member has been, Forbes dug into their known charitable giving and assigned each a philanthropy score from 1 to 5. Two-thirds of the billionaires on The Forbes 400 scored a 1 or 2, meaning they have given less than 5% of their fortune to charity. See the gallery for the 20 richest women in the U.S., with their net worths as of Sept. 8, according to Forbes.
