Cascades of Phone Calls Show Relationships Between States

Researchers sifted through a whole lot of AT&T mobile phone data to find out who’s talking to who—or, really, where’s talking to where. The Connected States of America, as the project is called, has produced some amazing maps showing clusters of communication, from the surprising—neighboring states like Oklahoma and Arkansas pair off, chatting mostly with each other—to the expected: the flood of continent-spanning calls between New York and San Francisco.

    What I find most surprising is the total lack of activity in the centre and north-centre of the country!

    Not all that surprising, they are mostly empty expanses. Go through Wyoming and you can go three hours on the highway without seeing a town beyond the small 10 person popup towns for service stations. Likewise, the area also has the worst cell service in the country (excepting Alaska), making it harder to track calls from or to there using AT&T data.

    I would have thought Boise would register to San Francisco. Oh well. We’re pretty self-sufficient.

    That might be the most boring video on YouTube.
