Bill Gates is the richest man in the world. This is how he gives away his billions.

Bill Gates turns 62 Saturday. The Microsoft founder has been keeping busy since he stepped down as CEO 17 years ago. Mainly, he’s been spending his enormous wealth — he’s the richest man in the world at a net worth of $87.9 billion — through the Bill & Melinda Gates Foundation he started with his wife.

As of the end of 2016, the charitable foundation had given away $41.3 billion in grants and currently has the largest endowment of any private foundation in the U.S. The Gates Foundation funds everything from malaria prevention in Mozambique to smoking cessation in China to college costs for kids in the U.S. (including the author — thanks, Bill!).

Here’s a breakdown of where the foundation allocated $4.6 billion in grants just last year. Click the buttons at the bottom to drill into or exit a category:
