Participation in a mobile app survey to collect expenditure data as part of a large-scale probability household panel: response rates and response biases
04 Oct 2017
We examine non-response in expenditure data collected with a mobile app: 2,432 members of the Understanding Society Innovation Panel in the UK were invited to download an app to record all their spending on goods and services for a month, by scanning receipts or reporting spending in the app. We examine participation at different stages of the process; the prevalence of potential barriers to participation, including access, ability and willingness to use different mobile technologies; and biases in the types of people who participate, considering socio-demographic characteristics, financial position and financial behaviours.
