Association of Psychometric Intelligence to Regional Demographic Variables

Abstract

The paper looks into the association of average psychometric intelligence (national IQ) with three demographic indicators: birth rate, infant mortality, and life expectancy. This association is analysed in a sample of 129 countries that are representative of the whole world community, and in a sample of European countries. In the 129-country sample all the three demographic indicators are highly associated with national IQ, whereas in a sample of European countries the association of birth rate with national IQ is not significant.
