Methodology: Circana conducts a monthly survey of US active gamers over the age of 13. Surveys are fielded online, via PC and mobile devices, drawing from a nationally representative pool. Respondents qualify on the basis of having played games in the past month (30 days). To ensure consistency across samples and correct for any biases/errors, Circana implements a weighting system for each monthly dataset based on representative distributions of platform use and platform investment. Circana’s models are based on aggregated, cross-product samples, and are updated quarterly to account for market shifts.
