Walking and cycling statistics presents data using two main sources, the National Travel Survey (NTS) and the Active Lives Survey (ALS).
The NTS is a household survey of personal travel by residents of England travelling within Great Britain, from data collected via interviews and a one week travel diary. The ALS is a household survey by residents of England, from data collected via a push-to-web survey.
Statistics from the National Travel Survey were assessed during 2010 by the UK Statistics Authority. An assessment reportwas published in October 2010. The statistics were confirmed as National Statistics in July 2011.
Statistics from the Active Lives Survey are Official Statistics. The department’s view is that all statistics which are not designated as National Statistics are robust and have been produced to a suitable standard. We welcome any feedback on these statistics.
