Zimbabwe District-Level Risk Indicators for Flood Assessment

Zimbabwe district-level indicators for flood hazard assessment provide demographic, infrastructure, and accessibility metrics across seven thematic layers. Produced by the Heidelberg Institute for Geoinformation Technology (HeiGIT) and updated in March 2026, the data aggregates WorldPop and OpenStreetMap sources for all admin level 2 divisions.

Use Cases

• Modeling flood impact on vulnerable groups using children_u5 and elderly population counts
• Planning emergency medical logistics based on access_pop_hospitals_30min and hospital_count
• Assessing educational infrastructure resilience by mapping education_count against flood_exposure indicators

Strengths

• Uses HDX COD-AB standardized administrative boundaries for interoperability
• Integrates high-resolution WorldPop demographic data for vulnerability mapping
• Provides specific travel-time accessibility metrics at 30, 60, and 120-minute thresholds

Limitations

• Potential under-representation of facilities in regions with low OpenStreetMap contributor activity
• Aggregated at admin level 2, which may mask localized vulnerabilities within large districts
