Bulgaria Risk Indicators: Admin Level 2 Flood and Infrastructure Data

HeiGIT generated this collection of subnational risk indicators for Bulgaria at the admin level 2 (district) scale, last updated in March 2026. It integrates geospatial data from OpenStreetMap, WorldPop, and Google Earth Engine to quantify flood exposure, demographic vulnerability, and service accessibility.

Use Cases

• Emergency response planning using access_pop_hospitals_30min to identify districts with limited medical reach during floods
• Disaster resilience analysis by comparing elderly population counts with flood_exposure indicators
• Infrastructure gap assessment using education_count and primary_healthcare_count relative to total population density

Strengths

• Admin level 2 granularity across all indicator categories
• Integration of openrouteservice (ORS) travel-time metrics for 30, 60, and 120-minute intervals
• Multi-source validation using WorldPop and OpenStreetMap data

Limitations

• Potential completeness variance in OpenStreetMap facility counts between urban and rural districts
• Dependency on HDX COD-AB boundaries which may change over time
