More than 10% of the world's nearly three thousand billionaires made a philanthropic commitment in support of COVID-19 response and relief efforts between January and May. According to the Billionaire Census 2020, billionaires who have donated were more likely to be in the tech industry and were more likely to be under the age of 50, to be self-made and to be wealthier. The share of women was larger among COVID-19 donors and those women were more likely to be self-made. The seventh edition of the annual study also found that the number of billionaires globally rose 8.5% in 2019, to 2,825, while their combined wealth grew 10.3%, to $9.4 trillion.
