Using SAMHDA

Accessing data

The data access requirements and procedures for Inter-university Consortium for Political and Social Research (ICPSR) projects differ based on factors such as funding sources and file types.

Data in the SAMHDA archive are freely available. Therefore, users do not need to obtain permission to access, analyze, or publish findings based on SAMHDA data. All users of SAMHDA data must abide by the Terms of Use Policy and we ask that users properly cite the data files.

Users should note that some of the data elsewhere in the ICPSR archive, which were acquired and processed through support of the ICPSR membership, are downloadable only by individuals at ICPSR member institutions. Other data may be freely available but require user login through an ICPSR MyData account.
