New Ten-Year Restricted-use NSDUH Data Released with Counties and Other Geographic Variables Added

The National Survey on Drug Use and Health (NSDUH): 10-Year Substate R-DAS (2002 to 2011) data are now available from the Substance Abuse and Mental Health Data Archive (SAMHDA) for online analysis using the Restricted-use Data Analysis System (R-DAS).

Variables available in the NSDUH 10-Year R-DAS file include a number of geographic variables not found in other R-DAS files. These variables identify a limited number of counties, core-based statistical areas, combined statistical areas, metropolitan divisions, and other geographic regions.

Other NSDUH R-DAS data files also available for analysis using the R-DAS are these:

Note: The NSDUH R-DAS data files do not allow for the creation of single-year estimates. The 10-year file permits pooled estimates for the entire 10-year period. Similarly, the 2-, 4-, and 8-year data files allow for pooled analysis of data in 2-, 4-, and 8-year periods, respectively.
