Controlling for cost of living would make sense, but why would you control for race or education?

- jeffbee 5y agoBecause I think you are trying to answer the question of whether giving a specific person more money would cause them to have more or fewer children. You want the marginal fertility associated with a given marginal change in wealth. If you don't control for other factors then you are just taking cultural influences (e.g. that possibly some national origins or races prefer larger families) and multiplying them by the association between that race and wealth (e.g. that some race within a given country is systematically impoverished). So, that would be an invalid analysis without the control.
