Are class gaps in economic mobility widening while race gaps narrow?
Core argument: Between the 1978 and 1992 birth cohorts, the intergenerational persistence of household income ranks for white children rose 28%, as adult incomes fell sharply for white children from low-income families and rose for those from high-income families.
Between the 1978 and 1992 birth cohorts, household incomes in adulthood fell sharply for white children growing up in low-income families. At the same time, incomes increased for white children growing up in high-income families. These divergent trends resulted in growing white class gaps, with the intergenerational persistence of household income ranks for white children increasing by 28%. The gap in average household incomes for white children raised in low-income (25th percentile) versus high-income (75th percentile) families grew from $17,720 in the 1978 birth cohort to $20,950 in the 1992 birth cohort. In contrast, incomes in adulthood increased across all parental income levels for Black children.
