The National Longitudinal Study of Adolescent to Adult Health (Add Health) public-use data is now available for download from Dataverse. Add Health is part of UNC’s Dataverse collection , hosted by The Odum Institute. Dataverse is a “federated” system in which data are archived and preserved at multiple institutions worldwide, ensuring long-term access to the data.
If you are interested in data not available in the public-use datasets, please see our restricted-use data page for information about the contract application process.
The data file crosswalk provides a comparison of the contents of the public-use and restricted-use files.
