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

HeiGIT produced this dataset of risk assessment indicators for Tunisia at the admin level 2 (district) scale, updated in March 2026. It aggregates demographic, infrastructure, and flood exposure data from sources like WorldPop and OpenStreetMap to support disaster resilience analysis.

Use Cases

• Flood risk modeling using access_pop_hospitals_30min to identify areas with poor medical access during disasters
• Demographic vulnerability analysis by mapping elderly and children_u5 populations against flood zones
• Infrastructure planning by evaluating education_count and primary_healthcare_count relative to district population density

Strengths

• Admin level 2 granularity for sub-national analysis
• Includes travel-time accessibility metrics (30min/1h/2h) derived from OpenRouteService
• Integrates multi-source data from WorldPop, OpenStreetMap, and Google Earth Engine

Limitations

• Potential data gaps in facility counts due to reliance on OpenStreetMap crowdsourcing
• Missing column definitions for the rural population and vulnerability tables in the provided schema
