National Travel Survey
1. Figures from 1985/86 are from the National Travel Survey. Earlier years are derived from other household surveys.
2. Figures prior to 1989 for Great Britain, rather than England only.
3. Figures prior to 1995 are based on unweighted data.
The figures in this table are National Statistics
The results presented in this table are weighted. The base (unweighted sample size) is shown in the table for information. Weights are applied to adjust for non-response to ensure the characteristics of the achieved sample match the population of Great Britain (1995-2012) or England (2013 onwards) and for the drop off in trip recording in diary data.
The survey results are subject to sampling error.
