NSDUH 2021 Methodological Resource Book (MRB)

Use this collection to provide context for estimates from the National Survey on Drug Use and Health (NSDUH). This collection includes materials used to conduct the survey, reports on how the survey was conducted, and reports on how the data were processed. The Statistical Inference Report details how the data were analyzed for reports and tables, which may be useful for data users looking to do their own analysis.

New items are added to the collection as they become available, so resources published in a previous MRB may not yet be available for 2021. However, there are generally few changes from year to year, and a report from a previous year may have the information you are looking for.
