Now we just really need to do the work, which we're doing, to get contraceptives out to women worldwide.

Housework comes first, so girls often fall behind in school. Global statistics show that it's increasingly girls, not boys, who don't know how to read.

Contraceptives unlock one of the most dormant, but potentially powerful assets in development: women as decision-makers. When women have the power to make choices about their families, they tend to decide precisely what demographers, economists, and development experts recommend. They invest in the long-term human capital of their families.

We have to look at it country by country. In places like the developing world where, as you say, in Mumbai, it's about five hours' gap between what a woman does and a man does. You have to start by recognizing the problem and talking about it, trying to change those roles.

Kids are falling through the cracks and nobody notices it. That to me is what's wrong with the school system.

My background was computer science and business school, so eventually I worked my way up where I was running product groups - development, testing, marketing, user education.

Women and girls face a whole host of issues. We start with health, so we work very deeply on maternal deaths, making sure that a mom doesn't die in childbirth, making sure that she has access, for instance, to AIDS medication.
