The Open Probability-based Panel Alliance (OPPA) consists of four probability-based panels: the GESIS Panel in Germany, the LISS Panel in the Netherlands, the Korean Academic Multimode Open Survey (KAMOS) in South Korea, and the Understanding America Study (UAS) in the USA. The Alliance facilitates cross-cultural survey research with probabilitybased panels across the globe, endorsing joint methodological standards to yield representative data.

In order to showcase the alliance, we would like to invite you to collect your data within
OPPA free of charge. Future data collection, though, will follow the pricing schemes that can be found on the OPPA website.
