Global Mind Project data in the United States: A comparison with national statistics

Objectives: To assess whether large-scale data collected by the Global Mind Project through online recruitment, aligns demographically with national statistics from traditional probability-based surveys.Methods: We compared data collected in the United States by the Global Mind Project (83,589 responses from 2020 to 2023) with time- and question-matched data from the American Community Survey, Household Pulse Survey, and American Trends Panel.Results: Demographic trends in the Global Mind Project data matched national statistics within 5% to 10%. Slight biases were observed, including an overrepresentation of single individuals, those with fewer friends, and those seeking mental health treatment. Conclusions: Online survey methods, when combined with quota-based recruitment and post-stratification, can yield data that closely reflect national demographic trends in census data. These findings support the utility of the Global Mind Project for real-time, scalable public health monitoring.
