Explanatory notes
The Sydney housing supply forecast is an estimate of the number of new dwellings that could be built under current zoning and planning controls, as well as current programs and initiatives and various market conditions and demand factors. It reflects current trends in residential construction and approval activity. These trends could potentially change in the future, as a variety of economic, social and other factors—many of which we cannot foresee—influence housing development. We create the forecast using standard inputs and assumptions and adjust it with annual variables to reflect current economic conditions and feedback. You can read out detailed method paper (PDF, 572 KB).
The Sydney housing supply forecast is the key data set for potential housing supply in the future. Obviously, underlying demand is an important factor in the housing market and therefore for supply. To understand potential future underlying demand, the department publishes an estimate of implied dwelling requirement as part of its 2019 population projections; this is based on projected population growth and household formation.
Forecast inputs and method
The forecast methodology we apply depends upon the prevailing development type and location. This reflects the nuanced approach built into the forecasting process. Figure 20 summarises the key inputs. You can find more information on the method, including the detailed dwelling type, geographic coverage and assumptions and variables, in the method paper (PDF, 572 KB).
