Each study conducted with the Panels is available in the Data Archive. There are 2 types of studies: Single-Wave Studies and Longitudinal Studies. Single-Wave Studies are studies which are conducted only once with the Panels. Longitudinal Studies are conducted multiple times over varying time periods, to obtain longitudinal data. For a Longitudinal Study, there is a parent Longitudinal Study that contains the metadata for the study, and a Longitudinal Wave for each wave in the study. Each of these three types of views contain different information in the Data Archive.
