Sex differences in the socioeconomic gradient of children's early development
Bibliographic record
Abstract
Sex differences in early child development (ECD) are well documented, as is the socioeconomic status (SES) gradient in early development outcomes. However, relatively little is known about whether the SES gradient in ECD outcomes varies by sex. This study examines whether the association between neighbourhood SES and developmental health outcomes of Canadian kindergarten children is different for girls than for boys. Individual-level child development data, collected using the Early Development Instrument (EDI), were combined with neighbourhood-level socioeconomic data from Statistics Canada's Census and Tax Filer databases. Using an SES index comprising 10 socioeconomic variables, we show a significant cross-level interaction between neighbourhood SES and sex in relation to children's developmental outcomes: the neighbourhood SES gradient in child outcomes is steeper for males than for females. This finding was consistent across all five developmental domains measured by the EDI, for overall developmental health, and across geographical regions in Canada. Further research using family-level SES data, data from multiple time points and countries, and qualitative studies would help to further contextualize the observed interactions.

How this classification was reachedexpand
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.
