Please note: these data contain variables that have never been completely cleaned for analysis, because of the steep cost of cleaning a complex multilevel dataset for every possible use. Most published applications of these data have begun with a thorough inspection and cross-check of every value for every variable used in the analysis. This fact has led to a proliferation of datasets created for single projects. All potential users are warned that the data in these downloads may contain wild codes, nonsense responses, and/or erroneous information.
