National IQs updated for 41 Nations
Richard Lynn*
University of Ulster, Coleraine, Northern Ireland

Average IQs for 113 countries have been presented in Lynn & Vanhanen (2006): IQ and Global Inequality. Augusta (GA): Washington Summit. In the current paper this compilation is extended and updated. New national IQs are presented for 25 countries and revised national IQs for 16 countries. Numerous cultural, biological, economic, political and medical correlates of country-level intelligence have been demonstrated in previous studies. It is recommended that the new and updated IQs presented in this paper should be used as the best estimates of the average IQs for these countries by scholars investigating these correlates.
