National IQ estimates are approximate and based on meta-analyses of available cognitive testing data (Becker, 2019; Lynn & Vanhanen, 2012; World Population Review, 2025). These scores reflect measured test performance and are influenced by education, nutrition, healthcare, and socioeconomic factors — they do not measure innate intelligence. Within-country variation is much larger than between-country differences. IQ tests developed in Western contexts may not translate fairly across all cultures. Interpret with appropriate caution.
