Trends in teen pregnancy rates from 1996-2006: A comparison of Canada, Sweden, U.S.A., and England/Wales
Bibliographic record
Abstract
This article summarizes and compares the most recent available data on ten-year teen birth/ abortion rates in Canada, Sweden, U.S.A., and England/Wales. From 1996 to 2005, the teen birth/abortion rate declined by 36.9% in Canada, 25% in the U.S,A, and 4.75% in England/Wales, and increased 19.1% in Sweden. In 2006, the lowest teen birth/abortion rate per 1,000 women aged 15-19 was in Canada (27.9) followed by Sweden (31.4), England/Wales (60.3), and the U.S.A. (61.2). With respect to teen birth rates, in 2006, Sweden (6.0), and Canada (13.7) had rates substantially lower than in England/ Wales (35.0) and the U.S.A. (41.9). Canadian interprovincia(/territorial differences in teen pregnancy rates, and percentage declines fronn 1996 to 2006, as well as declines among women aged 15-19, 20-24, and 25-29 are exannined. Potential factors contributing to trends in teen pregnancy rates are discussed.

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.
