Richard Lynn et al. J Biosoc Sci. 2005 Jan.

Abstract

Raven's Standard Progressive Matrices test was administered to a representative sample of 920 white, Mestizo and Native Mexican Indian children aged 7-10 years in Mexico. The mean IQs in relation to a British mean of 100 obtained from the 1979 British standardization sample and adjusted for the estimated subsequent increase were: 98.0 for whites, 94.3 for Mestizos and 83.3 for Native Mexican Indians.
