Fertility patterns of child migrants: age at migration and ancestry in comparative perspective
Bibliographic record
Abstract
This article examines the fertility of women who migrated as children to one of three OECD countries-Canada, the United Kingdom, and France-and how it differs from that of native-born women, by age at migration. By looking at child migrants whose fertility behavior is neither interrupted by the migration event nor confounded by selection, the authors obtain a unique perspective on the adaptation process as a mechanism that explains variation in observed foreign and native-born fertility differentials. The authors find patterns that are broadly consistent with the adaptation hypothesis-which posits that as migrants become accustomed to their host countries, their fertility norms begin to resemble those of the native population-and, on average, limited cross-national variation in fertility differentials. The effect of exposure to the host country, however, seems to vary by country of origin, a finding that underscores the importance of taking into account the heterogeneity of the foreign-born population.

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.
