Notes: Standard errors are in parentheses. MLDA = minimum legal drinking age; ref. = reference; n = 3,671,075, based on the 1990 and 2000 5% census microsamples, restricted to birth years 1960-1969. CGR is the course graduation requirement for each state; exit exam denotes that a state required that students pass an exam to receive a diploma.
