The Regions of the United States, Based on Phone Calls

Call Data Community Map

Based on cellular phone data, the Senseable City Lab at MIT has created maps of connections between U.S. counties. The resulting regions of the United States are remarkable, as seen on the map. Some states are divided, such as New York, Pennsylvania, and Nevada while in other instances, the connections between two states is significant, such as Arizona-New Mexico, Oklahoma-Arkansas, Alabama-Georgia, Tennessee-Kentucky, and New England. The SMS data and map tends to show more localized regions. What are your thoughts? Share them below in the comments...

I would bet that the calling patterns would be better displayed is a gradual change in shading instead of a sudden and dramatic change from one color to another. For example, it appears from looking at the map that almost nobody in Oklahoma calls any one in Texas.

I donít have the foggiest idea what this map shows.

There was a short discussion thread about this same study, last week, on the general “United States” section of http://www.city-data.com/forum . By the way, I find city-data.com/forum to be a fascinating website.

Yes Win, an interesting site but I still don’t understand the map. Too late I guess.

I agree with Don Hirschberg.

Where is the key to what the colors mean?

Not the easiest map to discern clearly.

Hi Don and Mary! I’m sorry if my post was confusing! Did you follow the link to the maps themselves? Each region of interconnectedness is a different color. -Matt

I think it is pretty interesting. Shows (I think) that most friends and relatives live close and most business is done “locally.”
