This dataset contains the latest available numbers of dwelling approvals by District from July 1991; the latest available numbers of net dwelling completions by District from July 2012; and the number of net dwelling completions for Greater Sydney Region by financial year since 1949-50. Data are collected from Australian Bureau of Statistics, Sydney Water, Hunter Water and Councils in the Central Coast and Illawarra Regions and analysed as part of the Department’s responsibilities to monitor residential housing activity. Dwelling Approvals refers to a residential development that has received the final approval to construct. Net dwelling completions refer to the difference between the number of completed dwellings compared to the existing stock, adjusted for demolitions. For example, a two-unit development that demolishes one house is counted as one net dwelling completion.
