No, they cluster in areas where people play Ingress. Large proportions of poorer people own smartphones – probably not quite as large a proportion as for the wealthy, but the difference isn’t as stark as it was with laptops and desktops. The smartphone demographics are a lot more diverse than the Ingress player demographics.
So my point is, the widespread ownership of smartphones was starting to narrow the digital divide, but mobile services whose data sets are crowdsourced from the behavior of white people will tend to widen it again.
