Abstract

This study examined early language abilities as a mediator of intergenerational socioeconomic status (SES). In a 30-year longitudinal study (N = 114, 98% White, 53% male, monolingual English speakers), participants were tracked from kindergarten to age 36 with measures of language, nonverbal IQ, academic achievement, and SES. Early language ability, independent of IQ, explained nearly a quarter (24%) of adult SES variance through two pathways. The persistence pathway (7.8%) showed language mediated 66% of intergenerational SES transmission. The mobility pathway (16.1%) showed language predicted deviation from family-based expectations, with twice the contribution to mobility as to persistence. Tenth-grade academic achievement added no reliable unique variance, suggesting language operates through mechanisms beyond formal education. Oral language emerges as a candidate mechanism linking family circumstances to adult socioeconomic outcomes.
