I recently saw Stefanie Gray's map of area codes mentioned in the rapper Ludacris's 2001 song "Area Codes". (Gray's interpretation that Ludacris "claims to have hoes" in all these of these area codes doesn't match the song.) I was curious about the location of the geographic mean center of the mentioned area codes, so I made my own map (below) from a shapefile of US telephone area codes available from ESRI. The mean center is in NE Arkansas, which makes sense given Ludacris's Atlanta connection. Here's a large version of the map.
