If you think that all the commuters around you are making your drive to work longer, you could be honking at the wrong target. You could even be in the wrong city.

According to a new analysis by the coworking space management platform Yardi Kube, traffic is one factor. But the real key to how long your commute takes is the number of people in the town where you live.

Such data is of great use to both employers as well as anyone else interested in an office building's performance. Not only is time spent commuting itself a taxing experience for workers, affecting their willingness to come to work in an office, but according to a recent study by Moody's Analytics, office vacancy rates rose more in metros where it takes workers longer to get to work.
