Le changement familial : aspects démographiques
Bibliographic record
Abstract
L'effondrement de la fécondité québécoise, qui s'enclenche au milieu des années 1960, s'accentue chez les cohortes des années 1970, où se manifeste l'attraction irrésistible de la famille de deux enfants. Au tournant des années 1980, la probabilité d'avoir un premier enfant est la seule à résister à la baisse généralisée des indices d'agrandissement des familles. Le mariage a aussi perdu de sa popularité, sans devenir anachronique ; dans la majorité des cas, l'union libre retarde le mariage sans l'empêcher. Les ruptures d'union, qui font de plus en plus partie de l'horizon du mariage, jouent contre la fécondité et favorisent le départ précoce des enfants. Ces changements observés dans le comportement démographique des familles sont autant de signes de l'affaiblissement des liens personnels qui structuraient l'ancien tissu social.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
