Ever wonder why your commute out of DeKalb County is so hard? Does it cross your mind as you sit parked on I-285 listening to the big-rig in the next lane gargle diesel while some dude’s stereo blares music you hate?

Well, if you have (or if you haven't, actually), perhaps it'll make you feel better to know you're not alone. More than 72 percent of the county's working residents leave the county to get to work, according to newly-released data from the Atlanta Regional Commission.

The ARC says almost 206,000 DeKalb residents leave the county for work, while only about 79,000 both live and work in the county.

That 72 percent rate puts DeKalb in better shape than Cherokee (79), Clayton (78), Douglas (81), Fayette (76), Henry (79) and Rockdale (81) counties, according to analysis by The Atlanta Journal-Constitution.
