This study examined connections between migration & suicidality among adolescents in Hong Kong using census & registration data. Relationships between suicidality & sociodemographic/psychological factors replicated those found in the literature. Duration of residence was found important for the study of suicide among migrants. In both bivariate & multivariate analyses, suicidality levels for short-duration (less than 10 years) adolescent migrants were very much lower than for their local-born counterparts, those for the long-duration (10 years) migrants were very much higher.
