Mobile device login and break-off in individual surveys

In this paper, we analyse the use of mobile devices, i.e. smartphones and tablets, in individual surveys of Statistics Netherlands in 2017.
Over the last five years, the mobile device penetration has strongly increased and mobile devices have become standard communication tools. At Statistics Netherlands, respondents are stimulated to respond online, but, to date, most of its questionnaires are designed for desktops/laptops.
We explore the proportion of mobile device logins, the proportion of device switches, the break-off rate and the average mobile device interview duration for a combined dataset of individual surveys. The exploration forms the starting point for mobile device data collection and questionnaire design strategies.
