I wonder how you all are defining a dwelling. For example, many villages have smaller buildings that are definitely man made but maybe storage or non-living space. There may also be larger buildings for cattle or community functions. Are those dwellings? I can’t imagine trying to distinguish the purpose of the building accurately, but it also seems like just marking all permanent buildings will give an inflated count.
Also, most of these homes are round fenced areas with one or more buildings attached. Is that one dwelling or more than one?
