Find reports that present findings and data for U.S. states based on results of the combined 2018 and 2019 National Survey on Drug Use and Health (NSDUH).
NSDUH is an annual survey of the U.S. civilian, noninstitutionalized population ages 12 years or older. The combined 2018 and 2019 NSDUH reports provide state estimates for select measures of substance use and mental health outcomes by age group (e.g., ages 12 or older, 12 to 17, 18 to 25, and 26 or older and 12 to 20 for alcohol measures). State and regional estimates are based on a small area estimation (SAE) methodology in which state-level NSDUH data are combined with county and sub-county level census data from the state.
The 2018-2019 NSDUH State Prevalence Estimates (PDF, Excel) provide prevalence estimates and 95% confidence intervals by age group. CSV files can also be downloaded.
A comparison of 2017-2018 and 2018-2019 NSDUH State Prevalence Estimates (PDF, HTML) provides prevalence estimates by age group.
A comparison of 2008-2009 and 2018-2019 NSDUH State Prevalence Estimates (PDF, HTML) provides prevalence estimates by age group.
The survey also includes maps for certain estimates and detailed tables including percentages and counts for each state, census region, and the nation, by age group.
The 2018-2019 NSDUH National Maps of Prevalence Estimates by State (PDF, HTML) show 2018-2019 estimates, sorted from lowest to highest for each measure, and divided into five categories. More information about quintiles used is available (PDF, HTML).
State and regional estimates are based on a small area estimation methodology in which state-level NSDUH data are combined with county and census block group/tract-level data from the state.
The 2018-2019 NSDUH: Guide to State Tables and Summary of Small Area Estimation Methodology Report (PDF, HTML) is a guide to the development and presentation of 2018-2019 state estimates. A summary of the methodology is included as well as sample sizes, response rates, and population estimates.
