The longitudinal Monitoring the Future (MTF) Panel study extends the work of the cross-sectional MTF Main study by following a subsample of graduating seniors through the entire adult life course. The selected respondents are surveyed every two years from ages 19-30. Starting at age 35, respondents are surveyed every five years, at ages 35, 40, 45, 50, 55, and 60 (FZ surveys). The FZ surveys cover many of the same topics as the 12th grade and follow-up surveys and include additional questions on life events and health.

This study contains only the age 35 survey data for the MTF longitudinal panel study participants that have reached age 35 (FZ1) through the 2021 data collection.

NOTE: Users must also request the core panel data file: MTF: Base Year and Follow-Up Core Panel Data, Ages 18-30, 1976-2021 (ICPSR 39223) because demographic information (e.g. sex, race/ethnicity) for the participants of the age 35 survey is included in the core panel data file.

Researchers can merge the Age 35 (FZ1) study data file with other MTF follow-up data in this series. This includes:

Please see the study documentation available on the MTF Panel series page for question-specific details, including content areas included in all survey forms.

HIGHLIGHTS of this update:

• Missing data coding has been changed/simplified in this release. Please see the User Guide for details.
• Panel analysis weights are now included in the data file instead of a stand-alone file. Please see the updated documentation for information.

Please be alert for variable coding differences between paper and web survey versions, especially for questions skipped based on answers to other questions. Note the following:

• The web-based version of the survey was introduced in 2020.
• Paper vs. Web coding differences will be most noticeable for the questions related to substance use, relationship/marital status, employment, and family composition.
• Users will need to explore their data using V35035 (89940:FZ PAPER OR WEB - RESPONSE) to look for and understand any coding differences.

Extensive work has been done to document the history and use of the MTF substance use disorder questions and criteria. Please see Substance use disorder criteria sums in the Monitoring the Future Panel Study (Occasional Paper No. 101)

The NLSY97 standalone data files are intended to be used by crime researchers for analyses without requiring supplementation from the main NLSY97 data set. The data contain age-based calendar year variables on arrests and incarcerations, self-reported criminal activity, substance use, demographic variables and relevant variables from other domains which are created using the NLSY97 data. The main NLSY97 data are available for public use and can be accessed online at the NLS Investigator Web site and at the NACJD Web site (as ICPSR 3959). Questionnaires, user guides and other documentation are available at the same links. The National Longitudinal Survey of Youth 1997 (NLSY97) was designed by the United States Department of Labor, comprising the National Longitudinal Survey (NLS) Series. Created to be representative of United States residents in 1997 who were born between the years of 1980 and 1984, the NLSY97 documents the transition from school to work experienced by today's youths through data collection from 1997. The majority of the oldest cohort members (age 16 as of December 31, 1996) were still in school during the first survey round and the youngest respondents (age 12) had not yet entered the labor market.

The Survey of Youth in Residential Placement (SYRP) is the only national survey that gathers data directly from youth in the juvenile justice system. The Office of Juvenile Justice and Delinquency Prevention (OJJDP) designed the survey in 2000 and 2001 to survey offender youth between the ages of 10 and 20. SYRP asks the youth about their backgrounds, offense histories and problems; the facility environment; experiences in the facility; experiences with alcohol and drugs; experiences of victimization in placement; medical needs and services received; and their expectations for the future. SYRP research provides answers to a number of questions about the characteristics and experiences of youth in custody including:

• Who are the youth in placement?
• What are their offenses?
• What are their family backgrounds?
• What are their expectations for the future?
• How are youth grouped in living units and programs?
• What activities are available in each facility?
• How accessible are social, emotional, and legal supports?
• What is the quality of the youth-staff relationships?
• How clear are the facility's rules?
• How clear is the facility's commitment to justice and due process?
• What methods of control and discipline do staff use?

SYRP's findings are based on anonymous interviews with a nationally representative sample of youth in custody during the spring of 2003 using audio computer-assisted self-interview (ACASI) technology. SYRP is the latest addition to two ongoing data collections that OJJDP designed and implemented in the 1990s. It joins the Census of Juveniles in Residential Placement and the Juvenile Residential Facility Census to provide updated statistics on youth in custody in the juvenile justice system.

SYRP bulletins, reports, and a simplified online analysis tool are available from the SYRP Project Web site.
