Dear TfL. Is it possible to give me (roughly?) an indication of the number of individuals who use the London Underground network each year? Not passenger journeys, but individual people who take at least one journey a year on the London Underground. It doesn't need to be exact, but a rough indication would be good. Thanks.

Thank you for your request received by Transport for London (TfL) on 18 August 2017 asking for the number of individuals who use London Underground.

Your request has been considered in accordance with the requirements of the Freedom of Information Act and our Information Access Policy. You asked:

We do not hold the information you requested as we do not have a measure for the number of individual customers who used the London Underground in a single year.

Please see the attached information sheet for details of your right to appeal as well as information on copyright and what to do if you would like to re-use any of the information we have disclosed.
