2008-2010 National Survey on Drug Use and Health
National Maps of Prevalence Estimates, by Substate Region

The 27 national maps presented here show 2008-2010 National Survey on Drug Use and Health (NSDUH) estimates for 362 substate regions that were ranked from lowest to highest for each measure and divided into 7 categories designed to represent distributions that are somewhat symmetric, as in a normal distribution.1 Colors were assigned to all substate regions such that the third having the lowest prevalence are in blue (121 substate regions), the middle third are in white (120 substate regions), and the third with the highest prevalence are in red (121 substate regions). The only exceptions were the three perception-of-risk outcomes shown in Figure 4 (marijuana), Figure 11 (alcohol), and Figure 16 (cigarettes), which have the highest estimates represented in blue and the lowest estimates represented in red to the reflect the inverse relationship between substance use and the perception of risk of using that substance. To further distinguish among the substate regions that display relatively higher prevalence, the "highest" third in red has been subdivided into (a) dark red for the 16 substate regions with the highest estimates, (b) medium red for the 33 substate regions with the next highest estimates, and (c) light red for the 72 substate regions in the third highest group. The "lowest" third is categorized in a similar way using three distinct shades of blue. In some cases, a group (or category) could have more or fewer substate regions because two (or more) substate regions have the same estimate (to two decimal places). When such ties occurred at the "boundary" between two groups, all substate regions with the same estimate were assigned to the lower group. Tables containing specific estimates for these substate regions are available on the 2008-2010 NSDUH substate Web page at http://www.samhsa.gov/data/NSDUH/substate2k10/toc.aspx. Individual State maps containing enlarged images of these substate regions also are available.2

End Notes

1 Revised Mental Illness Estimates: The Substance Abuse and Mental Health Services Administration (SAMHSA) has been publishing substate estimates of the prevalence (both percentages and estimated counts) of past year serious mental illness (SMI) and any mental illness (AMI) among adults aged 18 or older since the release of the 2008-2010 substate small area estimation (SAE) report. Estimates were based on a model developed in 2008. In 2013, SAMHSA developed a more accurate model for the 2012 data. This revised model incorporates the NSDUH respondent's age and indicators of past year suicide thoughts and depression, along with the variables that were specified in the 2008 model (Kessler-6 [K6] questions on psychological distress and an abbreviated set of questions on impairment in carrying out activities from the World Health Organization Disability Assessment Schedule [WHODAS]), leading to more accurate estimates of SMI and AMI. The SMI and AMI maps in this document use estimates that have been revised based on the new model. Other mental health measures in these maps, such as major depressive episode (MDE) and serious thoughts of suicide, were not affected. For further information on the revised model, see the NSDUH short report titled Revised Estimates of Mental Illness from the National Survey on Drug Use and Health at http://samhsa.gov/data/default.aspx.

2 The substate regions within Los Angeles County, California, shown on the national maps also appear as enlarged images in the individual State maps for California. Enlargements of specific substate regions other than for an entire State are unavailable in this set of 27 national maps.
