Yet little is known about the implications of wealth on children’s development because research has focused mainly on the role of wealth in shaping outcomes in adulthood. Using data from the National Longitudinal Survey of Youth (N = 8,095), we examine how family wealth relates to achievement and behavior problems during early childhood, middle childhood, and adolescence. Further, we explore whether links between wealth and children’s development vary by level of income and income volatility. Results show that wealth, controlling for income level and volatility, is uniquely related to both academic and behavioral development in early childhood, middle childhood, and adolescence. Moreover, evidence suggests that wealth plays a buffering role when it comes to protecting children’s development from the deleterious effects of low family income, especially as children grow older.
