Geography of intergenerational mobility and child development

Abstract

Recent research by Chetty and colleagues finds that children's chances of upward mobility are affected by the communities in which they grow up [Chetty R, Hendren N (2016) Working paper 23002]. However, the developmental pathways through which communities of origin translate into future economic gain are not well understood. In this paper we examine the association between Chetty and Hendren's county-level measure of intergenerational mobility and children's cognitive and behavioral development. Focusing on children from low-income families, we find that growing up in a county with high upward mobility is associated with fewer externalizing behavioral problems by age 3 years and with substantial gains in cognitive test scores between ages 3 and 9 years. Growing up in a county with 1 SD better intergenerational mobility accounts for ∼20% of the gap in developmental outcomes between children from low- and high-income families. Collectively, our findings suggest that the developmental processes through which residential contexts promote upward mobility begin early in childhood and involve the enrichment of both cognitive and social-emotional development.
