This analysis draws on data from the Substance Abuse and Mental Health Services Administration’s (SAMHSA) State Estimates on past-month alcohol use among adults aged 18 and older. The “share of adults who drink” reflects SAMHSA’s annual estimate of the percentage of adults reporting alcohol use in the past month during the specified survey year.
For each state, the year with the highest recorded share of adults reporting alcohol use—referred to as the peak year—was identified. The percentage-point change between that year and 2024 was calculated to show the magnitude of decline from each state’s highest level.
Because peak years differ across states, a separate 10-year comparison was conducted between 2014 and 2024 to provide an apples-to-apples view of trends over the same time period for all states. All changes were tested for statistical significance at the 90% confidence level using a z-test (threshold: z > 1.645). Instances where changes were not statistically significant are labeled as “not significant” in the data tables.
