Differences in intelligence across thirty-one regions of China and their economic and demographic correlates

This study reports the differences in intelligence across thirty-one regions of the Peopleʹs Republic of China. It was found that regional IQs were significantly associated with the percentage of Han in the population (r = .59), GDP per capita (r = .42), the percentage of those with higher education (r = .38, p < .05), and non-significantly with years of education (r = .32). sults of the multiple regression showed that both the percentage of Han in the region and the GDP per capita were significant predictors of regional IQs, accounting for 39% of the total variance.
