Note: Respondents were limited to those in the Part II sample who were 18–22 years old at the time of interview and had not graduated from college. Significant odds ratios (OR) are shown in bold and marked with an asterisk * (α=0.05).

^aAge 18 was used to determine STB prior to the typical age of beginning college.

^b“College entrants” were defined as both current students and college attriters.

^c“Secondary school graduates” were defined as all secondary school graduates who never entered college.

^d“All non-college attenders” were defined as those who never entered college whether or not they graduated from secondary school.

^eBased on a pooled within-survey logistic regression model adjusting for between-survey variation in the association of age-sex with student status.
