This projected growth reflects an increase of approximately 9.1% over the 16-year period.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, as released in 2024 with 2022 as the base year. For any SA2 areas not covered by this data, AreaSearch is utilising the NSW State Government's SA2 level projections, as released in 2022 with 2021 as the base year. Growth rates by age group from these aggregations are also applied to all areas for years 2032 to 2041. Moving forward with demographic trends, a population increase just below the median of national statistical areas is expected, with the area expected to grow by 783 persons to 2041 based on aggregated SA2-level projections, reflecting recording a gain of 9.1% in total over the 16 years.

AreaSearch assessment of residential development drivers sees a low level of activity in Marayong, placing the area among the bottom 25% of areas assessed nationally

Marayong has seen approximately 29 dwelling approvals per year over the past five financial years ending FY-25. This totals an estimated 145 homes. In FY-26, up to May, there have been 27 approvals. The average expected construction cost of new dwellings is $351,000.

There has also been $5.5 million in commercial approvals this financial year. Compared to Greater Sydney, Marayong has around two-thirds the rate of new dwelling approvals per person. Nationally, it ranks at the 52nd percentile for areas assessed. New development consists of 71.0% standalone homes and 29.0% townhouses or apartments, shifting from the current pattern of 88.0% houses.

This suggests decreasing developable land availability and changing lifestyle preferences. With around 312 people per dwelling approval, Marayong is considered a low density area. According to AreaSearch's latest quarterly estimate, Marayong is projected to grow by 732 residents by 2041. Given current construction levels, housing supply should meet demand adequately, potentially enabling growth beyond current forecasts.
