Marshall Islands Risk Assessment Indicators at Admin Level 2

HeiGIT produced these risk assessment indicators for the Marshall Islands in 2026 to support flood hazard analysis across seven thematic layers. The data aggregates demographic, infrastructure, and accessibility metrics at the admin level 2 using the GAIA Pipeline.

Use Cases

• Estimating flood impact on vulnerable groups by intersecting MHL_ADM2_flood_exposure with elderly population counts
• Identifying healthcare deserts using access_pop_primary_healthcare_30min metrics
• Planning emergency shelter capacity based on education_count and pop_u15 totals

Strengths

• Admin level 2 (ADM2) spatial granularity
• Integration of WorldPop, OSM, and Google Earth Engine data
• Pre-calculated travel-time metrics for 30, 60, and 120-minute intervals

Limitations

• Facility counts are subject to OpenStreetMap data completeness
• Missing specific record counts and file size metadata
