Annual domestic business trips in Great Britain 2010-2018

* From 2016 onwards a new data processing approach has been used. For this reason, the source advises caution when comparing 2016 data with earlier data. Later data is comparable with 2016 data and similarly, data before 2016 can be compared with earlier data without concern.
The source adds that the latest 2018 results are provisional and subject to minor changes in subsequent months due to the inclusion of trip-takers returning from late trips.

** Interviewing is carried out every week of the year using a face-to-face methodology. Annually, some 100,000 respondents are contacted, and any who have returned from an overnight trip within the past four weeks are asked to describe the details of that trip.
