This is a cross-sectional design because the researcher is measuring the preferences of different age groups at the same time. A longitudinal design would involve following the same group of individuals over time and measuring their changes in preferences. A nested design involves a subset of individuals within a larger group, and a panel design involves repeatedly measuring the same group of individuals over time.
