Now, Facebook says it has mapped almost 2 billion people better than any previous project. The company’s Connectivity Labs announced this week that it created new, high-resolution population-distribution maps of 20 countries, most of which are developing. It won’t release most of the maps until later this year, but if they’re accurate, they will be the best-quality population maps ever made for most of those places.
