Not sure if you read CIA 2013 Brief 2 (http://traveltrends.transportation.org/Documents/B2_CIA_Role%20Overall%20Tr… ) This gives a nice description of the complexities of commuting.

Hi! All, I got an interesting question from our management. They want to know if we can define a commuter by how many work trips this particular person make during certain period of time (a day, a week or a year). The simple definition I found online to describe a commuter is "a person who travels some distance to work on a regular basis." This brings up two basic questions: 1. How do we determine "some distance"? 2. How do we determine "regular basis"? I could not find a clear definition regarding commuter in Commuting in America III though we talked about commuter population throughout the report. Any insight on this would be greatly appreciated!

Interesting point - not sure that CIAIII covers it - I spent more time on it in the original CIA and CIAII. The easy, simple, operable definition that defines all the stats we have to work with is: a member of the labor force who worked last week. this in effect is the def of a worker by the Census - see Concept of a Worker pg 4 of Brief 3 in CIA2013.
