Key Features of UAS Teen:

• Comprised of teens aged 13-17 living in UAS households.
• Recruitment maintains the probability-based structure of UAS recruitment.
• Teens are invited to surveys independently of their parents’ participation. They are compensated for their survey time directly, not through parents.
• Data are linkable to other members of teens' household who participate in the UAS, and can be connected to:
  • Household-level demographics and histories
  • Previously submitted responses from family-linked respondents (e.g., parents, grandparents, other participating family members)
• Teens are contacted via SMS and email, and complete surveys online.

Sampling and Weights
Teen sampling weights build on UAS household base weights (which correct for differential probabilities of household inclusion) and incorporate teen-specific benchmarks from the American Community Survey (ACS), including:

• Age
• Gender
• Race/ethnicity
• Geographic location

These adjustments support population-level inference for U.S. teens, while acknowledging that additional selection processes - such as parental permission and teen willingness to participate - cannot be fully adjusted for using observed characteristics alone (ACS; U.S. Census Bureau ).
