What is it about?
Evolutionary biologists have suggested that rich individuals should invest more in their boys and poor individuals more in their daughters. We examine if this relationship is true for gender preferences for children, measured as the difference to progress to a new child based on the sex composition of previous children (due to dissatisfaction with the sex of the previous children). We find that there is no such pattern, and that all socioeoconomic groups desire a mix of boys and girls.
