Abstract
Background: Women outlive men in all but the poorest and most unequal of countries, despite recent increases in male life expectancy that have exceeded those amongst women. This study identifies sources of disparity in longevity between sexes. Methods: Canadian data on age and cause of all deaths recorded in 1999 are grouped and analyzed to identify sex differences in mortality. Results: The overall ratio of male to female deaths (1.09 to 1) varies across ages, from a maximum of 2.6 male for every 1 female death between ages 15 and 29 years, to a minimum of 0.80 to 1 amongst those over 74 years old. The source of greatest disadvantage for men under age 45 years is behaviours attributable to gender. Accidents, injuries, and suicides account for the majority of the male mortality excess in this group, and for more male than female deaths amongst all but the most elderly. Before age 60 years, risk-taking behaviour claims more male lives than does circulatory disease. Conclusions: Data presented show the significance of gender as a determinant of longevity, and suggest the value of interventions to ameliorate this effect.

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.
