Note: Data were drawn from the National Longitudinal Study of Youth 1997 cohort. Sample includes non-Hispanic white respondents with transcript data reported. Model 3 includes controls for parents’ education, household income, whether a student attended a private school, whether the mother is obese, and whether the student lives in an urban area. All models include fixed effects on census region and birth year; supplemental models without the fixed effects yielded no substantive difference in the coefficients of interest. All missing values imputed.
