title: Monitoring the Future Longitudinal Panel Mortality Data, 1976-2021 [Restricted-Use]
title: Version 1

description: 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).

description: The nationally-representative base year (BY) cohort sample (i.e. each high school senior class) was selected using a multistage area probability sample design involving three selection stages: (1) geographic areas or primary sampling units (PSUs), (2) schools (or linked groups of schools) within PSUs, and (3) students within sampled schools.
Each year, 2,450 respondents to the 12th grade survey were selected for biennial longitudinal follow-up. The panel sample was selected within school by form and sex, and each base-year school was required to have a minimum of two follow-up selections (individuals). The base year sampling weight was factored into the targeted sample size for each school/form/sex combination. An illicit drug user/nonuser stratification was created, based on responses to nine base year questions about 30-day drug use. (An individual was considered a "user" if they reported any use of LSD, hallucinogens other than LSD, cocaine, amphetamines, sedatives/barbiturates, tranquilizers, heroin, or narcotics other than heroin, or used marijuana 20 or more times in the past 30 days.) Illicit drug users were sampled at a 3-to-1 rate relative to non-users.
When the 12th grade respondents originally selected for follow-up reach age 35, they continue to be surveyed every five years at ages 35, 40, 45, 50, 55, and 60. Single questionnaires are presented at each age, covering many of the same topics as the age 19-30 surveys and including additional questions on life events, drug use, and health.
Please see Chapter 1 of the MTF Annual Panel Study Report for additional sampling details.
