This dataset provides 2011 Census estimates that classify the workplace population in England and Wales by method of travel to work. The estimates are as at census day, 27 March 2011.

This dataset uses the 2001 specification of travel to work. This information is produced using both a person's place of work and their method of travel to work and is comparable with 2001. For example, a person who has indicated their place of work as their home address and said that they travel to work by driving a car or van (eg visiting clients) appears in the category ""Work mainly at or from home"", as was the case in 2001.

Information on travel to work informs both national and local transport services and policies. It provides a basis for transport planning, for example, whether new bus routes or changes to existing bus routes are needed.

In order to protect against disclosure of personal information from the 2011 Census, there has been swapping of records in the Census database between different geographic areas, and so some counts will be affected. In the main, the greatest effects will be at the lowest geographies, since the record swapping is targeted towards those households with unusual characteristics in small areas.
