Family Income and Educational Attainment: A Review of Approaches and Evidence for Britain

It is widely recognized that, on average, children from poorerbackgrounds have worse educational outcomes than their better-offpeers. There is less evidence on how this relationship has changedover time and, indeed, what exactly leads to these inequalities.In this paper we demonstrate that the correlation between familybackground (as measured by family income) and educational attainmenthas been rising between children born in the late 1950s andthose born two decades later. We then consider the extent towhich these associations are due to the causal effects of incomerather than the result of other dimensions of family background.We review the approaches taken to answering this question, drawingmainly on the US literature, and then present our own evidencefrom the UK, discussing the plausible range for the true impactof income on education. Our results indicate that income hasa causal relationship with educational attainment.
