Antigua and Barbuda Risk Indicators: Sub-National Hazard and Access Data

HeiGIT produced this dataset in 2026 providing risk assessment indicators for Antigua and Barbuda at the administrative level 2. It aggregates demographic, infrastructure, and hazard exposure data from sources like WorldPop and OpenStreetMap to support flood and cyclone resilience analysis.

Use Cases

• Modeling disaster response needs by cross-referencing elderly population counts with cyclone_exposure layers
• Evaluating healthcare gaps using access_pop_hospitals_30min to identify underserved districts
• Planning educational infrastructure by analyzing education_count relative to rural_population distributions

Strengths

• Integrates data from WorldPop, OSM, and Google Earth Engine
• Provides specific travel-time metrics (30/60/120 min) for healthcare access
• Uses standardized HDX COD-AB administrative boundaries

Limitations

• Infrastructure counts like education_count are subject to OpenStreetMap contributor bias
• Geographic scope is restricted to a single small island nation
