This "Economic Insights" article documents postsecondary enrolment rates among 19-year-olds over the 2001-to-2014 period by province of parental residence, parental income and sex. The data are drawn from the T1 Family File. Postsecondary enrolment is determined by the tuition, education and textbook credits on the personal income tax files. Parental income refers to the adult equivalent, after-tax income of parents, expressed in 2014 constant dollars. Youth are grouped by parental income quintiles. Overall, the results suggest that the percentage of 19-year-olds enrolled in a postsecondary education program increased steadily from 2001 to 2014 among youth from all families, but particularly at the bottom of the income distribution. Enrolment rates increased faster among Eastern provinces compared to Western provinces, while young men and women both registered similar gains in enrolment rates throughout the period.
