Brain development may be influenced by socioeconomic status (SES), a marker of a family’s income and parental education. SES differences may result in exposure to extra stress during critical periods of neurodevelopment. We performed the first longitudinal analysis of differential brain development in 70 healthy infants and young children (1 year to 6 years of age) stratified by familial SES using high resolution T1 MRI. We demonstrated that trajectories of subcortical and cortical maturation are significantly different between infants and children from low and high SES families over the first 6 years of life.
