## 🎯 Project Overview
This notebook interrogates the claim by SAPS Crime Registrar
Major-General Thulare Sekhukhune that reported rape cases decreased
by 3.2% in Q3 FY2025/26 — and places that claim within two decades
of femicide surveillance data published by the South African Medical
Research Council (SAMRC).
Produced from the perspective of a **private security analytical
division** conducting occasional work with SAPS, this notebook
applies rigorous data science methodology to one of South Africa's
most critical public health and safety challenges.

## ❓ Research Questions
1. Is there truly a decrease in reported rape as stated by
Maj-Gen Sekhukhune?
2. What does the SAMRC's 20-year femicide surveillance data
reveal that SAPS statistics cannot?
3. Which provinces and demographics are at highest risk?
4. What does statistical modelling predict for FY2025/26
and FY2026/27?
