Data documentation

Click on each dataset’s name to see its description, license, citation, and link to its original source. Code used to create these data can be found here.

Every dataset here has been modified. IRW does not redistribute source files: each one is reshaped into the IRW data standard — long format, one row per person-item response, with columns renamed and non-response material dropped. The processing script for a given dataset is the record of exactly what was changed, and is linked above. The license shown beside each description is the source’s license, which continues to govern reuse of that dataset: where it carries a non-commercial restriction, that restriction travels with IRW’s copy.
