In this paper, we examine the effect of income on child development in the United States and the United Kingdom, as measured by scores on cognitive, behavioral, and social assessments. In line with previous results for the United States, we find that for both countries income generally has an effect on child development that is positive and significant, but whose size is small relative to other family background variables.
