 Analysing the information available in the various census surveys, the most important common features for classifying the building stock according to the expected seismic response were selected: i) predominant material of the exterior walls, ii) material of the floor, iii) type of dwelling, and iv) type of area (urban or rural). None of the surveys included information about the number of storeys, nor the lateral load resisting system, and only the census from Venezuela made reference to the year of construction. Analysing the information available in the various census surveys, the most important common features for classifying the building stock according to the expected seismic response were selected: i) predominant material of the exterior walls, ii) material of the floor, iii) type of dwelling, and iv) type of area (urban or rural).

 +The number of dwellings in each region was estimated based on the census information of each country. The table bellow shows the information available in each census database. Regarding housing information,​ the most important common features for classifying the building stock according to the expected seismic response were selected: i) predominant material of the exterior walls, ii) material of the floor, iii) type of dwelling, and iv) type of area (urban or rural).

 The reason why four attributes were selected is due to the capability of downloading disaggregated data from the different web-based applications. For Colombia and Venezuela the type of dwelling was not included because disaggregation of data was only available for a maximum of three attributes. Note that the first version of the regional mapping scheme for South America presented in the previous progress report only considered two attributes for building classification:​ the typical material used on the exterior walls and floor. The reason why four attributes were selected is due to the capability of downloading disaggregated data from the different web-based applications.
