The Social Science Variables Database (SSVD) enables AHRQMCC users to examine and compare variables and questions across studies or series. The SSVD only includes a subset of our collection. For a comprehensive search of all datasets, use our data search in the left column, which indexes all of the documentation available for our studies, including the variable descriptions.

The SSVD builds on a pilot project funded by the National Science Foundation (NSF). It demonstrates the benefits of using structured variable-level documentation in XML, tagged according to the Data Documentation Initiative (DDI) standard.
