The power few missing persons: A ten-year follow-up study of over 2000 youth missing persons
Bibliographic record
Abstract
Youths going missing continues to be a matter of great concern for the police. This group has been consistently found to comprise most police missing person reports, be more likely to go repeatedly missing, and experience victimization and vulnerability related to these incidents. This study thus sought to examine single versus repeat versus habitual/chronic missing youth cases to extract differentiated insights to initiate discussions on proactive policing efforts for reducing and preventing missing youth cases. Data employed tracked 2126 young people reported missing for the first time in 2005, for ten years using their police records. Over a third went missing more than once. There was evidence of the power few hypothesis, with the habitual/chronic cases recording over 60% of the missing person reports across the study period, and clear differences emerged between single, repeat and habitual/chronic cases in terms of their demographics, mental health concerns, and justice involvement.

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.
