In 2013, Americans worked an average of 47 hours per week, including the time they spent commuting to and from work.
That's according to a recent study from the New York City Comptroller's office, based on the most recent Census and American Community Survey microdata.
The study found that workers in some cities - like San Francisco and Houston - put in more hours than the average American. While those in places like Detroit and Phoenix worked less.
Following our list of the 15 hardest working cities, we created a map of the top 30, broken down by weekly hours worked and commute time.
