The National Survey on Drug Use and Health (NSDUH) is designed to provide substance use and mental illness estimates of the U.S. civilian, non-institutionalized population ages 12 years or older for 395 substate regions. These documents present U.S. substate estimates for 15 measures of substance use and mental illness based on combined 2014 to 2016 NSDUHs.
These estimates are based on a small area estimation (SAE) methodology in which substate-level NSDUH data are combined with county and census block group and tract-level data from the 50 states and the District of Columbia.
The 2014-2016 NSDUH Overview and Summary of Substate Region Estimation Methodology includes:
The 2014-2016 NSDUH National Maps of Prevalence Estimates by Substate Region estimates for 395 substate regions ranked from lowest to highest for each measure and divided into seven categories.
The 2014-2016 NSDUH Substate Region Definitions include tables and maps defining the substate regions. A Guide to Merging Definitions is also available for merging with external data sources.
A Comparison of 2012-2014 and 2014-2016 NSDUH Substate Region Estimates - tables showing comparisons of the 2012-2014 and 2014-2016 substate area estimates.
A Comparison of 2008-2010 and 2014-2016 NSDUH Substate Region Estimates - tables showing comparisons of the 2008-2010 and 2014-2016 substate area estimates.
Tables of p-values for within year comparisons across substate regions and a Guide to P-Value Tables are available.
