Digitalisation has great potential to reduce costs, improve access and enhance user experience. However, it could also increase inequality, with some people struggling to access and use digital services. It is important to understand who is likely to be excluded in this way and why. This can help to identify groups at particular risk of digital exclusion, inform efforts to overcome the barriers, and develop more inclusive digital services. This paper introduces a set of five linked datasets examining a range of user factors affecting the use of digital services. The datasets focus on the use of digital mobility services, but the data is useful in understanding the use of other digital services as well. The user factors considered include technology access, use and competence and attitudes towards digital technology. The datasets were the results of surveys in five European regions and countries (Germany, Italy, Barcelona Metropolitan Area, Flanders and the Netherlands). Samples were taken of the adult (age 16+) population with a total of 3,454 participants.
