Regional Differences in Intelligence and their Social and Economic Correlates in Finland

Regional differences in IQ are reported for Finland showing that average IQs are highest in the south, containing the capital city of Helsinki. It is proposed that the selective migration of those with higher IQs to Helsinki has been the major factor responsible for the higher average IQ in the south. Regional IQs are positively correlated with the percentage of the population with tertiary education, mean income, and average male and female life expectancy; and negatively with the percentage of the population with average income less than 60% of the national median, the percentage of unemployment, and the rate of infant mortality.
