Abstract: The Trivers Willard hypothesis – that higher maternal quality is associated with a higher sex ratio – is tested using a large population survey from 12 European countries. Several outcomes are studied, the proportion of children born who are male and the sex of the first three children. The principal explanatory variables of interest are mother’s education, marital status and age at birth. Little evidence, if any, of such a relationship is found.
