The Detroit Metro Area Communities Study (DMACS) is a panel survey of Detroit residents aged 18 and older. The original panel of respondents was drawn from an address-based probability sample of all occupied Detroit households in 2016 and has since been refreshed through additional address-based sampling annually. Between August 6, 2025 and October 1, 2025, 3,170 previously enrolled panelists were invited to participate in a self-administered online or interviewer-administered telephone survey.

Topics included: household composition; housing status; perceptions of neighborhood; social connection and loneliness; election; mayoral priorities; crime and safety; violence reduction; artificial intelligence; flood management; mental health; employment.

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:

• MTF: Base Year and Follow-Up Core Data, Ages 18-30, 1976-2021 (ICPSR 39223)

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)
