The United States of Connectedness

Mobile phones have helped close the gap between people, connecting friends, family and co-workers across wide distances. But the lines of communication don't follow traditional state and city boundaries and instead reflect different social influences and relationships that are sometimes harder to understand.

But a new data and visualization project called the Connected States of America helps bring some focus into the way mobile phones facilitate communications and shows how conversations and text-messages bind areas and regions together, even ones that are far apart. Researchers at the MIT Senseable City Lab, AT&T Labs-Research and IBM Research today have showed off their work, which takes anonymous aggregated AT&T mobile phone data and creates interactive maps illustrating where calls and text messages are placed and where they connect to. The maps show what areas are likely to be in communication with each other and how some places, sometimes in the same state, remain separated. Metropolitan regions, even ones that spill over state lines, understandably facilitate a lot of communications among people in one area. But there is a lot of back and forth that emerges between states too. For instance, Alabama and Louisiana are sister states because of the cellular traffic between the two, while parts of Tennessee, like Chattanooga break away from the rest of Tennessee and join other neighboring states.
