The National Survey on Drug Use and Health (NSDUH): 10-Year Substate R-DAS (2002 to 2011) data are now available for online analysis using the Restricted-use Data Analysis System (R-DAS). more...
Variables available in the NSDUH 10-Year R-DAS file include a number of geographic variables not found on 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:
- NSDUH: 2-Year R-DAS (2002-2003, 2004-2005, 2006-2007, 2008-2009, and 2010-2011) produces combined two-year estimates for 2002-2005 and 2006-2009;
- NSDUH: 4-Year R-DAS (2002 to 2005 and 2006 to 2009) produces combined four-year estimates for 2002-2005 and 2006-2009; and
- NSDUH: 8-Year R-DAS (2002 to 2009) produces estimates based on a combined 8 years of data.
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.
