Description

Graphed by me based on data from The Inter-cohort Trends in Vocabulary Test Scores for Blacks and Whites controlling for social background. This implies that the observed upward intercohort trend for Blacks is related to an improvement in social background. For Whites, however, improvement in social background across time does not raise test scores correspondingly. [1]
