Benin Risk Assessment Indicators: District-Level Accessibility and Demographics

Benin risk assessment indicators aggregated at the admin level 2 (district) scale, produced by HeiGIT and updated in March 2026. The data integrates demographic, environmental, and infrastructure metrics from WorldPop and OpenStreetMap to facilitate flood hazard analysis.

Use Cases

• Assessing healthcare reach by analyzing the access_pop_hospitals_30min column
• Identifying high-risk zones for flood response using the children_u5 and elderly demographic fields
• Quantifying educational infrastructure density via the education_count field

Strengths

• Aggregated at the granular admin level 2 (district) scale
• Integrates multi-source data from WorldPop, OpenStreetMap, and Google Earth Engine
• Provides specific travel-time accessibility metrics (30, 60, 120 minutes) to hospitals

Limitations

• Potential data gaps in facility counts due to reliance on OpenStreetMap crowdsourcing
• Temporal staleness if OpenStreetMap or WorldPop source data is not current
