Brain drain is an increasingly important concern for local governments in northern communities in Canada in maintaining and enhancing human capital levels to sustain vibrant economies and communities. Researchers, however, have yet to examine the magnitude of north-south out-migration nor do we know the characteristics of youth who are likely to relocate. Our study contributes to this knowledge gap by employing multiple waves from Statistics Canada's Youth in Transition Survey (Cohort A) linked to each youth's reading scores from the Programme for International Student Assessment (measured at age 15), and longitudinally to their tax filer information until age 30 (T1 Family Files).
