There are several surveys conducted by the Census Bureau that ask questions related to commuting including means of transportation, time of departure, mean travel time to work, vehicles available, distance traveled, and expenses associated with commuting. Commuting (Journey to Work) refers to a worker’s travel from home to work. The U.S. Census Bureau released updated County-to-County Commuting Flow data in early March 2013. The data is based on information collected in the 2006 – 2010 American Community Survey, five year estimates. Place of work refers to the geographic location of the worker’s job. A worker is defined as a person 16 years old and over, who were employed and at work during a reference period.
