The G20 leader’s summit came to a close earlier this month in Istanbul, Turkey. The emphasis of Turkey’s G20 presidency this year is on “inclusive and robust global growth.” Turkey recognizes inequality as a major problem within countries as well as across national borders and stresses the need for reducing inequality in order to achieve mutual growth. In this article, I examine the relationship between income inequality and health among G20 countries. I find that as income inequality lessens, key health outcomes, such as child mortality and life expectancy, also improve substantially. This is an important finding that could provide guidance for ADB member economies in formulating their domestic policies to foster inclusive growth.
