While extreme poverty rates around the world have decreased by more than half since 1990, one in five people in developing regions still lives below the international poverty line. In addition, the gap between rich and poor is widening. Brazil, for example, has the eighth-largest economy in the world but one of the widest income inequality gaps. Even in the United States, more than 40 million people live in poverty. Access to adequate health care and health-related infrastructure is also a growing concern across the globe. The Green School faculty is producing leading research on racial and gender inequality, health and society discrepancies, gentrification, minorities and marginalized communities, and the complex role of globalization in both ameliorating poverty and concentrating wealth.
