This reflects an increase of 1,994 people (12.2%) since the 2021 Census, which reported a population of 16,379 people.

This population level equates to a density ratio of 16,259 persons per square kilometer, which lies in the top 10% of national locations assessed by AreaSearch, making land in the area a highly sought resource. Waterloo's 12.2% growth since the 2021 census exceeded the state (7.8%) and Greater Sydney, marking it as a growth leader in the region. Population growth for the area was primarily driven by overseas migration, which contributed approximately 90.6% of overall population gains during recent periods.

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. Considering the projected demographic shifts, a significant population increase in the top quartile of statistical areas analysed by AreaSearch is forecast, with the area expected to expand by 8,047 persons by 2041 based on the latest annual ERP population numbers, reflecting an increase of 43.4% in total over the 17 years.

Employment drivers in Waterloo are experiencing difficulties, placing it among the bottom 20% of areas assessed across Australia

Waterloo features a highly educated workforce, with the technology sector a particular standout in terms of representation, and an unemployment rate of 8.5%. As of December 2025, 10,573 residents are in work while the unemployment rate is 4.3% above Greater Sydney's rate of 4.2%, showing room for improvement, and workforce participation is broadly similar to Greater Sydney's 70.2%. Based on Census responses, a high 58.5% of residents were found to work from home, though Covid-19 lockdown impacts should be considered.

Leading employment industries among residents comprise professional & technical, finance & insurance, and health care & social assistance. The area demonstrates a particularly notable concentration in professional & technical, with employment levels at 1.7 times the regional average. Conversely, health care & social assistance shows lower representation at 9.6% versus the regional average of 14.1%. The predominantly residential area appears to offer limited employment opportunities locally, as indicated by the count of the Census working population versus the resident population.

Based on AreaSearch analysis of SALM and ABS data, the 12-month period saw the labour force decrease by 0.3% while employment declined by 1.2%, causing the unemployment rate to rise by 0.8 percentage points. This contrasts with Greater Sydney, where employment rose by 2.2%, the labour force grew by 2.3%, and unemployment rose marginally. Jobs and Skills Australia's national employment forecasts from May-25 can offer further insight into potential future demand within Waterloo. These projections, covering five and ten-year periods, have been mapped against the local employment profile to estimate growth patterns. While national employment is forecast to expand by 6.6% over five years and 13.7% over ten years, growth rates differ significantly between industry sectors. Applying these industry-specific projections to Waterloo's employment mix suggests local employment should increase by 7.2% over five years and 14.3% over ten years (please note this is a simple weighting extrapolation for illustrative purposes and does not take into account localised population projections).
