This dataset provides 2011 estimates that classify usual residents aged 16 to 74 in England and Wales by their method of travel to work. The estimates are as at census day, 27 March 2011.

Travel to work estimates from the 2001 Census, for example in UV39, are not compatible with this estimates in this dataset because of the differences in the way that people who indicated that they work from home but also have a method of travel to work have been handled. Estimates that are compatible with 2001 are available in dataset CT0015.

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.
