Ever wondered just how common your last name is? Well, the folks at National Geographic are offering up this super fascinating map that allows you to zoom in on different areas of the country and see what the most common surnames are and what their probably provenance is. It's fascinating to see not only the effects of migration of different groups, but also to see the varying population densities laid out so plainly. It's especially compelling to zoom in and out and around and learn each region's difference—knowledge that will definitely come in handy if you're trying to escape from the law and need to create an alternate identity! Just pick a common name specific to the region your fleeing to, and they'll never be able to find you. And if all else fails go with Smith or Johnson.
