Gates Foundation Annual Letter
(If all girls received 12 years of high-quality education, women’s lifetime earnings would increase by as much as $30 trillion, which is bigger than the entire U.S. economy.) Preterm birth affects mothers in every part of the world—although some groups experience it at a higher rate (which Melinda will talk about), and premature babies in low-income countries are much more likely to die than ones in richer countries. I can’t think of anything else that affects 10 percent of people in every part of the world but gets so little attention.
