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.
As we are aware that some users will also want to compare these data with the 2001 Census, we published an additional table on 13th February, to present the 2011 data on the 2001 basis (so mobile hairdressers will count at working at home) at a Local Authority level. As these data are less accurate than those in the Quick Statistics table, we have no plans to produce this table at lower levels of geography as a standard product. However, those data could be commissioned, subject to Statistical Disclosure Control.
When we produce "flow data" outputs, respondents who have a method of travel to work but no destination (e.g. the mobile hairdressers) will not be included, as there is no flow that can be shown. These data will be on a comparable basis to outputs from the 2001 Census.
