The method of travel used for the longest part, by distance, of the usual journey to work. This topic is only applicable to people who were in employment in the week before the census.
The data on travel to work are not directly comparable between 2001 and 2011, because of a change to how they were processed.
In 2001, if a respondent recorded that their Workplace Address was "at home", it was assumed that they did not travel for work, and they were also recorded as working at home in the Travel data.
However, in 2011, this assumption has not been made. Therefore, any respondent who works at home, but also travels (e.g. a mobile hairdresser) is recorded as "Working at home" in data or Workplace (which has not yet been published) but as "Driving" (or whichever mode of travel they recorded) in the Travel data.
This is more relevant to transport planners and other users.For data comparable with the 2001 data see "Census: Method of travel to work (2001 definition)"
