If you invest in a girl or a woman, you are investing in everybody else.

In the United States, there's definitely some controversy about birth control in general, and I think we needed to split the debate and have people realize that we actually agree as a country about contraceptives. Over 93 percent of American women say they use contraceptives, and they feel very good about it.

When I look at 225 million women who want contraceptives, and then I look at the 52 million unintended pregnancies that could be avoided by addressing this unmet need, where can we have the biggest impact with our voice, our dollars, our partners? It's on contraceptives. I would rather address the problem upstream.

My undergraduate work was in computer science and economics. It just happened to be at that time when 34 percent of computer-science majors were women. We didn't realize it was at the peak at the time.

Birth control has almost completely and totally disappeared from the global health agenda, and the victims of this paralysis are the people of Sub-Saharan Africa and South Asia.

Despite the debunking, you have a small group in the last five years that hasn't wanted to vaccinate their children, for instance, for measles. Then, all of sudden, we got an outbreak of measles and kids were starting to die from measles.

I am Catholic, I was raised Catholic, I am a practicing Catholic. But I say we need to agree to disagree. We have a shared mission around poverty, and I focus on that, because we do a lot with the Catholic Church around poverty alleviation. I'm always looking for: what is the common thread? What do we care about? What do we believe in? We believe in women around the world. We believe in all lives have equal value.
