Samoa exposure#
This page summarises the exposure model for Samoa in Oceania, including national, subnational, and taxonomy-level views.
National summary#
The national exposure profile by occupancy class highlights the distribution of buildings, replacement value, and exposed population.

Subnational summary#
The subnational summary aggregates exposure by first administrative level and supports comparison of spatial concentration of assets.
