In November 2013, a month after the publication of this study, the UK Office for National Statistics realised that it had made a minor error in the preparation of the ‘travel to work’ 2011 census data which forms the basis of this report. This error concerned the process whereby people were identified as working from home on the basis of their reported place of work, and re-allocated to the ‘work at or from home’ response option on the travel to work question. Having identified the error, the Office for National Statistics re-issued the relevant census 2011 tables on 18/11/2013.

Comparison of the original and the replacement sets of tables indicates that a net total of 104,748 adults (0.44% of the England and Wales commuter population) were initially wrongly re-allocated to the ‘working at or from home’ response category. As such, the total number of commuters in England and Wales is not 23.7 million, as reported in this paper, but rather 23.8 million. Including these additional 100,000 commuters in the analyses presented in this paper has no important impact upon the percentages presented, with most being unchanged to two decimal places. For example, in the published version of this report the 2011 modal share for travel to work in England and Wales is 10.912% for walking, 3.115% for cycling, 17.767% for public transport and 67.127% for private motorised transport. Using the newly-corrected tables, these percentages are 10.910% for walking, 3.115% for cycling, 17.750% for public transport and 67.143% for private motorised transport. Thus all substantive findings reported in the published version of this paper continue to apply using the corrected, re-released census datasets which can now be found on the Office for National Statistics website.
