 So, I love maps, and this is actually one of my favorite maps of all time. It's kind of a mash-up between population density and average income per capita. And you can read it as this kind of ranked list of places, places where it's relatively easy to conduct research and learn about people's opinions and their thoughts. And then, you know, places that are where it's actually quite difficult to get insight into the underlying dynamics of the populations there. So, as an American, it's relatively easy for my voice to be heard, but, you know, a typical Kenyan has a much more difficult time having their voice be heard, and we're learning about their themselves. So, we've built the world's largest compensation platform to enable us to be able to better understand underserved, understudied populations around the world. We have the ability to instantly compensate 3.48 billion people in exchange for their data, in exchange for their opinions. And we compensate them with prepaid airtime in over 72 different currencies. So, the bank, the World Bank is actually starting to use this type of technology to try to figure out, for example, what is the price of a kilo of rice in a local market in Nicaragua or in Bangalore? The Gates Foundation is interested in whether people are using bed nets and their attitudes towards different types of preventative malaria measures. We thought it might be fun to actually start using this technology to just get a better sense globally of what's happening and what are people thinking? And so, we've asked now over 5 million people in over 100 countries a wide range of different questions, and compensating themselves with prepaid mobile airtime for NPR's Planet Money show. Adam Davidson used this to ask people around the world, what would people do with $15? And the range of responses were extraordinary from someone in Uganda who wanted to buy a domain name to someone in India who needed to pay a dowry. So, we can instantly generate this type of data, and it's hard not to see patterns in it. And things that are surprising. Nigerians are very bullish about their economy. They love Nokia. And things that are not necessarily so surprising, such as Brazilians loving their love for soccer. When we actually started asking about education, some of the interesting results were that people in India were 10 times as likely to say education was the reason why they didn't have job opportunities than people in Brazil, for example. Now, if you start looking in the realm of nutrition, individuals living in Nigeria turn out to be 5 times as likely as people in South Africa to buy food based on their nutritional value rather than its taste. So, we're actually starting to start looking at outcomes of interest here that are, you seem to be characterizations of countries in general. When it comes to the environment, people's attitudes towards recycling are radically different in a place like the Philippines and Brazil, where people are 3 times as likely to recycle and to take action to promote the environment than people living in Russia, for example. The gender differences, because we can split this in a lot of different ways, but if you look at men and women and you take India, for example, Indian males are 3 times as likely to watch long amounts of television than Indian females. And that's one of the other interesting things, is that you can now segment this based on the regional differences. So, if you take Indonesia, for example, rural Indonesians are something like 5 times as likely to drink more than one soda in a given day than urban Indonesians. And so, we're actually starting to pull out differences not just within, between countries, but within a country. And if you look at these divisive, controversial issues, like in South Africa, 90% of the population believe that they should have the right to own a gun, whereas in a country like the Philippines, less than half of the population believes that that's the case. So, stepping back a little bit, there's now 5 billion active mobile subs on the planet today, the majority of which are living in emerging markets, and a large fraction of which are very eager to earn very small amounts of prepaid airtime to have their voice be heard, to be able to participate in this platform. And I'm going to conclude this talk by announcing that we're now opening this up. So, it's not just available to the UN and the World Bank and brands, but to the public at large. So, you can log in, you can click your country, you can target your demographic, and you can field a question. And it will go out to one of these 3.48 billion people who are actually now starting to be able to compensate with prepaid airtime. And so, I'm going to leave you today with the question, now that we have the ability to ask virtually half of our species a question, what would you ask? How should we put this technology to use? Thank you.
