IQ rating by countries

"IQ and the Wealth of Nations" was the book published in English in London in 2002. The authors of the book were Dr. Richard Lynn, distinguished retired professor of psychology at the University of Olstera and Dr. Tatu Vanhanen, distinguished retired professor of Political Science, at the University of Tampere.

The book states that the differences in national income (in the form of GDP per capita) is correlated with differences in the average national IQ (IQ).

The authors interpret this correlation as an indicator that coefficient of intelligence is an important factor in making a difference in national wealth and economic growth, but IQ is not the only determining factor for these differences.
