•	Openfile summarizing the methods used to develop a national model of physical exposure that can be used for natural hazards risk assessments, including findings about the current state of physical exposure in Canada to earthquakes, floods, hurricanes, landslides, and wildfires.

•	Summary of the key findings from the study

/datasets/nhsl_physical_exposure_indicators_s.gpkg
•	The national physical exposure model dataset, grouped according to settled areas (i.e., polygons), which are areas that approximately delineate clusters of buildings across Canada. In cities, settled area boundaries generally correspond with census dissemination areas (Statistics Canada, 2016), but in rural areas where census dissemination areas can span more than thousands of square kilometers, these boundaries approximately correspond to areas where buildings are situated. Summary statistics about buildings and populations within each settled area boundary are provided to support with understanding the general patterns of physical exposure across Canada at the neighborhood scale. 

/datasets/nhsl_physical_exposure_indicators_b.gpkg
•	According to building archetypes (i.e., points) within settled areas, where a building archetype represents a collection of buildings of similar occupancy type, construction type, and design level. These groups are represented as point locations at the centroid of the corresponding settled area, and each settled area can have multiple groups of buildings corresponding to different building archetypes present within that area.

•	A dictionary of attributes included in the national physical exposure model datasets.
