Turkey Risk Assessment Indicators: District-Level Flood and Demographics

Turkey risk assessment indicators at the district level (admin level 2) produced by HeiGIT in 2026. The data aggregates demographic, infrastructure, and flood exposure metrics derived from WorldPop, OpenStreetMap, and Google Earth Engine. It provides specific accessibility and vulnerability layers to support disaster resilience analysis.

Use Cases

• Evaluating healthcare gaps by analyzing access_pop_hospitals_30min across different districts
• Identifying high-risk populations for flood events using children_u5 and elderly demographic columns
• Emergency shelter planning based on education_count and primary_healthcare_count distributions

Strengths

• Aggregated at admin level 2 for localized district-scale analysis
• Includes specific travel-time accessibility metrics (30, 60, and 120 minutes) rather than simple Euclidean distance
• Integrates data from multiple validated sources including WorldPop and OpenStreetMap

Limitations

• Facility counts are dependent on OpenStreetMap data completeness, which may vary by region
• Demographic data is derived from WorldPop estimates rather than a direct recent census
