Plot a heat map of mobile operating systems, and the geography of wealth illuminates. Go to Manhattan. It’s all Apple IOS. Head to New Jersey, or out to the Bronx, where average household income plummets, and it’s Android. In L.A., if you live in Malibu, Beverly Hills, the Palisades, you have an iPhone. South-Central, Oxnard, and Inland Empire—you own an Android. The iPhone is the clearest signal that you are closer to perfection and have more opportunities to mate.
