Future trends predict exceptional growth, placing the area in the top 10 percent of Australia's non-metropolitan areas, with an expected expansion of 19,535 persons by 2041, reflecting a gain of 94.1% over 17 years based on latest annual ERP population numbers.

The level of residential development activity in Thornton - Millers Forest was found to be higher than 90% of real estate markets across the country

Thornton - Millers Forest has seen approximately 347 new homes approved annually. Over the past five financial years, from FY-21 to FY-25, around 1,738 homes were approved, with an additional 130 approved in FY-26 so far. On average, each dwelling constructed over these years has attracted about 3.3 new residents annually.

This high demand coupled with the new supply indicates potential price growth and increased buyer competition. The average construction value of new dwellings is around $270,000, which is lower than regional levels, suggesting more affordable housing options for buyers. In FY-26, there have been approximately $4.9 million in commercial approvals, reflecting the area's predominantly residential nature. Compared to the rest of NSW, Thornton - Millers Forest exhibits 82.0% higher construction activity per person, which has recently eased but remains well above national averages, indicating strong developer confidence in the area. The new building activity is primarily focused on detached houses (74.0%) and attached dwellings (26.0%), maintaining the area's traditional low-density character with a preference for family homes. This shift from the existing housing stock (currently 95.0% houses) suggests decreasing availability of developable sites and changing lifestyle preferences.

According to the latest AreaSearch quarterly estimate, the area is projected to add approximately 18,692 residents by 2041.
