Abstract
The 'Illegitimacy Bonus,' part of 1996 welfare reform legislation, awarded $100 million in each of five years to the five states with the greatest reduction in the nonmarital birth ratio. Three states -- Alabama, Michigan, and Washington DC -- won bonuses four or more times each, claiming nearly 60% of award monies. However, in none of these three states was the decline in the nonmarital birth ratio linked to increases in proportions married, and only in Michigan was it linked to declines in nonmarital (relative to marital) fertility within demographic groups, behavioral changes that the Illegitimacy Bonus was presumably intended to reward. Shifts in the racial composition of births accounted for 1/3 (Michigan), 2/3 (DC) or all (Alabama) of the decline in the nonmarital birth ratio. The non-marital birth ratio fell most in DC, averaging 1.5 percentage points per year over the award period. However, the number of black children born in DC fell by nearly one half from 1991 to 2001. Changes in population composition alone primarily a decline in the number of black women aged 15 to 34 can account for the entire decline in the nonmarital birth ratio in DC between 1990 and 2000.

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.
