Organisation profile

The Belgian Online Probability Panel (BOPP) is an advanced data infrastructure co-owned by all Belgian universities and intended to boost and integrate interdisciplinary research in behavioral and social sciences. The panel consists of 4,000 Belgian citizens (16y+), randomly selected from the National Register. Respondents regularly receive short online surveys. Respondents without internet access can fill out a postal questionnaire. BOPP fields a yearly core
questionnaire to collect basic information (e.g., economic situation, household composition, work, social and political attitudes, health) on all panelists. For the remaining questionnaire, researchers from all fields can apply to field their surveys. After anonymization, public use files of the integrated data are made available to the whole research community. BOPP facilitates the linkage of these survey responses to administrative data.
BOPP offers access to high-quality, representative data, collected fast and cost-effectively. The infrastructure generates new opportunities for longitudinal analyses, interdisciplinary research, experimental research designs and linking collected data to administrative and context data.
