This dataset provides a municipal‑level hazard index representing exposure to aircraft movement across KwaZulu‑Natal. Weighted flight‑routes, airport operation zones, elevation modifiers, and settlement‑exposure layers were aggregated within municipal boundaries to quantify the relative aviation‑hazard environment for each municipality.

A composite metric that multiplies or weights aviation‑hazard severity with population‑exposure values to reflect the relative risk to people living beneath or adjacent to flight‑path corridors. Municipalities with high‑severity flight routes and larger populations receive proportionally higher scores.
FlightSeverityAndPopulation = Route_Importance_Class_Severity × Population_Exposure_Index
