It’s worth noting that this is not from Craigslist at all, but an outside analysis of the cities from the craigslist site and approximates the geographic areas covered by each. A complete post about how this map was generated is available here, and they have even made all of the data files available in a number of different formats. Bonus!
Craigslist doesn’t care about state lines, counties, time zones or voting districts. They care about defining an area that covers certain population levels that effectively use their service.
