Substate estimates for 25 measures of substance use and mental disorders based on the combined 2008, 2009, and 2010 National Surveys on Drug Use and Health (NSDUHs) are provided. NSDUH is an ongoing survey of the civilian, noninstutionalized population of the United States aged 12 years or older. All estimates presented here are based on a small area estimation (SAE) methodology in which substate-level NSDUH data are combined with county and census block group/tract-level data from the State.
NOTE: SAMHSA has released revised NSDUH estimates of mental illness among adults aged 18 or older. Revisions are due to improvements in methods for estimating mental illness. The improvements resulted in estimates of mental illness that are more accurate, particularly for young adults. As a result, State estimates of serious mental illness and any mental illness provided in the detailed tables are revisions to previously released estimates. For more information on the revisions see http://www.samhsa.gov/data/2k13/NSDUH148/sr148-mental-illness-estimates.htm and http://www.samhsa.gov/data/2k12/NSDUHrevisedMImethods2012/NSDUHrevisedMImethods2012.pdf. Also see Section B.10.1 in the substate methodology report.
For information on other revisions to previously released estimates, see Section A.4 in the substate methodology report.

A table showing ranges of prevalence estimates for each outcome categorized into seven groups from lowest to highest estimate for age groups 12 to 17, 18 to 25, 26 or older, and 18 or older. Information from these tables can be used by users who wish to develop State or national maps similar to those produced for the 12 or older age group. (PDF - 55.0 KB)
