Armenia Risk Assessment Indicators: Admin Level 2 Flood and Demographic Data

Seven thematic layers of risk indicators for Armenia provide district-level data on flood exposure, demographics, and service accessibility. Produced by HeiGIT using the GAIA Pipeline, the data aggregates WorldPop and OpenStreetMap sources to support disaster resilience analysis at the administrative level 2.

Use Cases

• Evaluating healthcare gaps by analyzing access_pop_hospitals_30min relative to elderly population counts
• Identifying districts with high flood risk using ARM_ADM2_flood_exposure to prioritize infrastructure reinforcement
• Calculating school-age population density using pop_u15 and education_count for resource allocation

Strengths

• Integrates multi-source data from WorldPop, OpenStreetMap, and Google Earth Engine
• Provides specific travel-time accessibility metrics (30/60/120 min) for healthcare via openrouteservice
• Uses standardized HDX COD-AB administrative boundaries for ADM2_PCODE fields

Limitations

• Facility counts like hospitals_count are subject to OpenStreetMap data completeness which varies by region
• Aggregated at admin level 2, which may mask hyper-local variations in flood risk
