Unit Definitions (Census)
  1998 2008
Dwellings A building is generally a single structure on the ground. It is covered by a roof and usually enclosed within external walls or with common dividing walls with adjacent buildings. In some areas the very nature of construction of houses is such that there may not be any wall. For example a conical roof almost touches the ground and an entrance is also provided and there will not be any wall as such. Such structures should be treated as buildings.
