BOPP - building the Belgian Online Probability Panel (Research)

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 residents (16y+), randomly selected from the National Register. Panelists regularly receive short online surveys. Panelists without internet access can fill out a postal questionnaire. BOPP fields a yearly core study questionnaire to collect basic information (e.g., economic situation, household composition, work, social and political attitudes, health) from all panelists. For the other time slots, 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 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.
