Abortion has become a very politicised issue that I think countries have to work out themselves. In a lot of countries, people can't even yet agree on what their laws should be.

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.

I am inspired by the women I meet everywhere I go. They have to work so hard just to make sure their families survive, but somehow they stay optimistic and do everything in their power to make the future better than the past.

But iPods and iPhones are two things we don't get for our kids.

With economic opportunity, sometimes it's making sure that if they're not in a place where they can have good jobs, that when they have economic opportunity, they have digital tools to use.

In places like India with smartphones, there's an app now for women if they're in a violent situation, they can press one button. They've given their cell-phone number to five trusted friends, and right away their GPS location goes out: "Here I am."

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.
