This series is calculated by dividing the aggregate travel time to work for all workers by the total number of workers, 16-years old and older, who commute. The data is comprised of estimates found in tables B08013 and B08012 of the American Community Survey (U.S. Census), respectively.
The date of the data is the end of the 5-year period. For example, a value dated 2015 represents data from 2010 to 2015.
