The Chronicle of Philanthropy publishes an annual list of the top 50 philanthropists (both individuals and couples) by calculating their yearly donations. In 2017, America's wealthiest residents donated $14.7 billion to nonprofit organizations. About 60% of the total was donated by people who made their fortunes in tech, suggesting America's philanthropic center is shifting away from Wall Street and towards Silicon Valley, according to The Chronicle. America's wealthiest people donated $14.7 billion in 2017 to causes, alma maters, foundations, and charities — more than doubling the amount given away in 2016, reported Forbes.
