South Africa Risk Assessment Indicators: Admin Level 2 Flood and Demographic Data

Risk assessment indicators for South Africa aggregated at the admin level 2 (district) level, produced by HeiGIT in March 2026. It integrates demographic, infrastructure, and accessibility data from WorldPop and OpenStreetMap to facilitate flood hazard and resilience analysis.

Use Cases

• Identifying districts with low healthcare access using the access_pop_hospitals_30min column
• Calculating flood vulnerability by cross-referencing ZAF_ADM2_flood_exposure with children_u5 population counts
• Planning educational infrastructure based on education_count and pop_u15 demographics

Strengths

• Aggregated at admin level 2 for localized district analysis
• Integrates travel-time accessibility metrics from openrouteservice
• Combines demographic data with infrastructure counts from OpenStreetMap

Limitations

• Data quality is dependent on OpenStreetMap contributor activity in South Africa
• Aggregated district-level data may obscure hyper-local risk variations within a single district
