This visualization does not have the most current data available. You can find an updated visualization here.
The data for this visualization comes from the American Community Survey which is conducted by the U.S. Census Bureau. I used the Census Bureau API to pull the 2015 5 year estimate for the mean commute time in each county. Once I had gathered the data, I used Tableau to create this visualization.
I have included the API code I used to pull the data below. Mean travel time to work (minutes) is represented by DP03_0025E. You will need a free API key to access the data. You can find out more at the Census Bureau’s Developer Page. If you want to see what counties have the longest and shortest commutes in the country, click here.
