Congo Brazzaville: District-Level Risk and Flood Exposure Indicators

HeiGIT released this collection of risk assessment indicators for Congo Brazzaville in 2026, focusing on flood hazard analysis at the administrative level 2. The data integrates demographic, infrastructure, and accessibility metrics derived from WorldPop and OpenStreetMap for all districts in the country.

Use Cases

• Flood risk modeling using access_pop_hospitals_30min to identify areas with poor emergency medical access
• Demographic vulnerability analysis by mapping children_u5 and elderly populations against flood exposure zones
• Infrastructure planning by evaluating education_count and primary_healthcare_count across different districts

Strengths

• Aggregated at administrative level 2 for localized district-level analysis
• Integrates multi-source data including WorldPop demographics and OpenStreetMap infrastructure
• Includes specific travel-time accessibility indicators (30/60/120 minutes) derived from openrouteservice

Limitations

• Infrastructure counts like hospitals_count are dependent on OpenStreetMap completeness, which varies by region
• Potential temporal lag between source data (WorldPop/OSM) and the 2026 aggregation date
