Monitoring the Future Longitudinal Panel Mortality Data, 1976-2021 [Restricted-Use]

Since 1976, Monitoring the Future (MTF) has enrolled ~2,450 individuals each year from its nationally representative annual sample of 12th graders into the MTF Longitudinal Panel study. A primary goal of the MTF study is to examine potential consequences of substance use across the life course, including mortality. Therefore, the MTF Longitudinal Panel study now includes measures of mortality linked to the National Death Index (NDI). The MTF Longitudinal Panel Study Mortality Data 1976-2021 file includes MTF Longitudinal Panel members from the high school cohorts of 1976-2021 whose mortality status was confirmed through either (a) the MTF NDI match process (limited to high school cohorts 1976-2019) or (b) the MTF panel tracking process (including 1976-2021 cohorts, tracking through August 2025).
