Methodology

Data Confidence: Low (3/7 signals available)

Limited data available. Treat scores as rough estimates.

Data Sources

Geographic and population data from GeoNames. Climate data from Open-Meteo historical archive (2023). Daylight and prayer times computed with SunCalc algorithms. All calculations are deterministic and reproducible.

What These Scores Measure

Scores are based on geographic and climate signals only — temperature, elevation, daylight patterns, and nearby city density. They do not account for water infrastructure, governance, economic development, or disaster preparedness. A high score means favorable natural conditions, not necessarily strong resilience in practice.

Score Formula

The overall resilience score is a weighted average of five sub-scores: Climate Stability (25%), Connectivity (25%), Exposure & Terrain (20%), Water Security (15%), and Daylight Stability (15%). Each sub-score ranges from 0 to 100.

Score Bands

High (70+) Moderate (40-69) Low (<40)
