  1. All models adjusted for time fixed effects and cohort fixed effects and are weighted on total number of enrollments in each cohort-year, with 5th and 95th percentile weight truncation Model (1) is a crude model. Model (2) adjusted for urbanicity and GSD SES characteristics. Model (3) adjusted for urbanicity, GSD SES characteristics, student racial compositions and student SES characteristics. *p < 0.1, **p < 0.05, ***p < 0.01
