Trinidad and Tobago: Risk and Flood Indicators at Admin Level 2

Trinidad and Tobago risk indicators at administrative level 2, produced by HeiGIT using the GAIA Pipeline. The data integrates WorldPop demographics, OpenStreetMap infrastructure, and flood exposure metrics to support disaster resilience analysis. Updated as of March 2026, it provides localized metrics for flood hazard assessment across seven thematic categories.

Use Cases

• Analyzing healthcare accessibility by comparing access_pop_hospitals_30min against flood_exposure levels
• Identifying high-risk zones for pediatric emergency response using children_u5 and education_count
• Evaluating district-level resilience by aggregating hospitals_count and primary_healthcare_count

Strengths

• Admin level 2 granularity for all indicators
• Integration of travel-time accessibility data from openrouteservice
• Standardized ADM2_PCODE join keys for HDX COD-AB boundaries

Limitations

• Facility counts like hospitals_count depend on OpenStreetMap completeness which varies by region
• Temporal lag between source data from WorldPop/OSM and the aggregated indicators
