Youth Suicide Prevention Cost-Effectiveness
Public Policy • Python • Data Modelling • Impact Evaluation
Overview
Independent impact analysis using Japanese police suicide statistics and nonprofit outreach data. Extracted police suicide data from 120+ Japanese PDF reports, built a structured database, and modelled hotline, school outreach, and workshop impact under uncertainty.
Goal: estimate how many youth lives may be saved through workshops, hotline support, and school awareness outreach.
