Everyone’s heard about the “cycle of poverty.” But what about the cycle of prosperity?

In this new video, Melinda Gates explains how providing women and girls with access to contraception can help them create more prosperous futures for themselves, their families, and their communities.

When couples choose to have fewer children, more can be invested in each child’s health and education. Children who grow up healthy and stay in school are more likely to get a job and earn income, and, in turn, invest in health and education when they have children of their own. On a larger scale, a better educated populace could help fill the gap for skilled workers in developing economies, resulting in increased employment, productivity and GDP growth.

Family planning helps start the cycle, and there’s no time to waste. That’s why the Gates Foundation (and PAI!) support Family Planning 2020 (FP2020), which aims to get contraception into the hands of 120 million new users by 2020. Learn more here.
