The “children of Bill 101” generally refers to the youth of immigrant background (1st and 2nd generations), regardless of their mother tongue. These youth appear to choose French as their language of schooling in CEGEPs more often than suggested by the official data based solely on allophone youth. Thanks to the longitudinal nature of the data, their language choice is shown to vary widely with characteristics such as generation status, geographic origin, mother tongue/language spoken at home and residential location. Also examined are the retention at the university level of the CEGEP language of schooling and possible links between school perseverance and language choice in CEGEPs.
