Sample Design

Cross-sectional panel survey. The SnackTrack sample is designed to provide a representative sample of the U.S. population based on U.S. Census Bureau statistics for individuals ages 2 years and older.

The survey invitation is sent to the adult panel member in the household. In households with children younger than age 13 years, the child may help complete the survey, the adult may complete the survey on behalf of the child, or the adult may answer the survey for himself/herself. In households with teens ages 12 to 17 years, the teen may participate in completing the survey for himself/herself, or the adult may answer on the teen’s behalf. The sampling strategy is designed to provide a nationally representative sample based on U.S. Census Bureau statistics for individuals ages 2 years and older.

Sample Size

More than 350,000 snack food occasions annually.
