The Healthy Immigrant Effect in Canada: A Systematic Review
Bibliographic record
Abstract
Canada’s immigration admissions policy calls for individuals with high human capital (Knowles, 2007). Given the strong links between human capital and health (Jasso et al., 2004) and previous research which suggested the presence of a seemingly universal foreign-born health advantage among Canada’s migrant population, we expected to see the healthy immigrant effect across the life-course and for multiple health outcomes. What we found instead was a pattern much more complex than previously envisioned. Our review uncovered a clear survival advantage for immigrants, owing in part to positive self and state selection processes (at least for non-refugee migrants). However, there is greater variation in the healthy immigrant effect for morbidity. Moreover, viewed through the lens of different life-course stages, we uncovered a strong foreign-born health advantage in adulthood but less so during the perinatal period, childhood/adolescence, and late life. Immigrant selection may be less relevant for the very young and very old, and of course we should thus not expect the presence of a healthy immigrant effect for these groups if that is the case. But even during adulthood when the healthy immigrant effect appears to be most effective, some discrepancies still remain between different immigrant subgroups depending on the type of health measure used (e.g., greater variation for self-rated health but less variation for mental health, disability/functional limitations, risk behaviors, and chronic conditions).

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
