 The average floor area for structures of each typology was estimated using UESF data for each commune, because census data does not provide information on floor areas of dwellings. For multi-story buildings, the average floor area considers the built area of all stories. For emergency timber houses, and for informal houses an average floor area is not estimated because the total cost of these structures are estimated directly with the number of structures. The average floor area for structures of each typology was estimated using UESF data for each commune, because census data does not provide information on floor areas of dwellings.

 Ministry of Housing and Urbanism (MINVU) defines the costs per unit of area for five quality categories of residential structures: from superior to inferior. Ministry of Housing and Urbanism (MINVU) defines the costs per unit of area for five quality categories of residential structures: from superior to inferior.
  
-For the National Exposure Model, it is not possible to calculate the category for each structure based on any of the statistical data used. Typical structures were considered for the main building materials (reinforced concrete, masonry, timber and adobe), and it was possible to establish the best and worst qualities for each type of structure with its reposition ​costs related.+For the National Exposure Model, it is not possible to calculate the category for each structure based on any of the statistical data used.

-As the communes in the whole country does not have the same reposition ​costs, it is necessary to differentiate costs between them. The Internal Revenue Service (SII) has information of base appraisal values for residential structures with the same five categories than MINVU. This base appraisal value is modified by four factors dependent on the structure’s location, special conditions of the structure, depreciation,​ and a commercial coefficient applicable to structures built in commercial zones. The factor that depends on the structure’s location is assigned for each commune, from 1.0 to 0.4. To estimate the replacement cost of structures in each commune, the cost associated to best quality of construction was assumed for structures in communes with factor 1.0, and the cost associated to worst quality of construction was assumed in communes with factor 0.4. For other communes, the replacement cost is extrapolated according to its factor.+As the communes in the whole country does not have the same replacement ​costs, it is necessary to differentiate costs between them.

 Replacement cost for emergency and informal houses are not defined by MINVU. Then, it was assumed to be the same as the construction cost of a new emergency house: an average of USD 1,280. Replacement costs for informal houses are considered the same as for emergency houses because after an earthquake, damaged informal houses would be replaced with emergency houses by the authorities or helping institutions. Replacement cost for emergency and informal houses are not defined by MINVU.
