Mongolia Risk Assessment Indicators: District-Level Flood and Demographic Data

Seven thematic layers of risk assessment indicators for Mongolia are aggregated at the district level (admin level 2) to support flood hazard analysis. Produced by the Heidelberg Institute for Geoinformation Technology (HeiGIT) in March 2026, the data integrates demographic, infrastructure, and accessibility metrics from WorldPop and OpenStreetMap.

Use Cases

• Calculating the percentage of vulnerable residents using 'children_u5' and 'elderly' columns
• Evaluating disaster resilience by comparing 'hospitals_count' with 'access_pop_hospitals_30min'
• Spatial flood risk modeling using the 'MNG_ADM2_flood_exposure' layer

Strengths

• Aggregated at admin level 2 for sub-national analysis
• Includes specific travel-time accessibility metrics (30, 60, 120 minutes)
• Derived from the standardized HeiGIT GAIA Pipeline

Limitations

• Potential data gaps in rural areas due to reliance on OpenStreetMap crowdsourced data
• Lack of specific column definitions for the vulnerability and rural population layers
