Transport for NSW provides projections of population and dwellings at the small area (Travel Zone or TZ) level for NSW. The latest version is Travel Zone Projections 2024 (TZP24), released in January 2025. TZP24 replaces the previously published TZP22. The projections are developed to support a strategic view of NSW and are aligned with the NSW Government Common Planning Assumptions. The TZP24 Population & Dwellings Projections dataset covers the following variables: Estimated Resident Population Structural Private Dwellings (Regional NSW only) Population in Occupied Private Dwellings, by 5-year Age categories & by Sex Population in Non-Private Dwellings The projections in this release, TZP24, are presented annually from 2021 to 2031 and 5-yearly from 2031 to 2066, and are in TZ21 geography. Please note, TZP24 is based on best available data as at early 2024, and the projections incorporate results of the National Census conducted by the ABS in August 2021. Key Data Inputs used in TZP24: 2024 NSW Population Projections – NSW Department of Planning, Housing & Infrastructure 2021 Census data - Australian Bureau of Statistics (including dwellings by occupancy, total dwellings by Mesh Block, household sizes, private dwellings by occupancy, population age and gender, persons by place of usual residence) For a summary of the TZP24 projection method please refer to the TZP24 Factsheet. For more detail on the projection process please refer to the TZP24 Technical Guide. Additional land use information for workforce and employment as well as Travel Zone 2021 boundaries for NSW (TZ21) and concordance files are also available for download on the Open Data Hub. Visualisations of the population projections are available on the Transport for NSW Website under Data and research/Reference Information. Cautions The TZP24 dataset represents one view of the future aligned with the NSW Government Common Planning Assumptions and population and employment projections. The projections are not based on specific assumptions about future new transport infrastructure but do take into account known land-use developments underway or planned, and strategic plans. TZP24 is a strategic state-wide dataset and caution should be exercised when considering results at detailed breakdowns. The TZP24 outputs represent a point in time set of projections (as at early 2024). The projections are not government targets. Travel Zone (TZ) level outputs are projections only and should be used as a guide. As with all small area data, aggregating of travel zone projections to higher geographies leads to more robust results. As a general rule, TZ-level projections are illustrative of a possible future only. More specific advice about data reliability for the specific variables projected is provided in the “Read Me” page of the Excel format summary spreadsheets on the TfNSW Open Data Hub. Caution is advised when comparing TZP24 with the previous set of projections (TZP22) due to addition of new data sources for the most recent years, and adjustments to methodology. Further cautions and notes can be found in the TZP24 Technical Guide Important note: The Department of Planning, Housing & Infrastructure (DPHI) published the 2024 NSW Population Projections in November 2024. As per DPHI’s published projections, the following variables are excluded from the published TZP24 Population and Dwellings Projections: Structural Private Dwellings for Travel Zones in 43 councils across Greater Sydney, Illawarra-Shoalhaven, Central Coast, Lower Hunter and Greater Newcastle Occupied Private Dwellings for Travel Zones in NSW. Furthermore, in TZP24, the Structural Private Dwellings variable aligns with the 2024 Implied Dwelling projections while the Occupied Private Dwellings variable aligns with the 2024 Households projections at SA2 level prepared by DPHI. The above variables are available upon request by contacting model.selection@transport.nsw.gov.au - Attention Place Forecasting.

Data files and papers for the 2014 release of the NSW population projections.

These projections are an update of the 2013 preliminary NSW population projections and account for the impact of the Australian Bureau of Statistics’ (ABS) decision to revise 20 years of historical population estimates for the period 1991-2011.

The 2014 projections also consider findings from the 2011 Census and the latest data and expertise on fertility, mortality and migration at the time of release.

These projections have since been superseded. The latest release is the 2024 NSW population projections, published in November 2024. The 2024 projections are available at https://www.planning.nsw.gov.au/data-and-insights/population-projections.

Official NSW population projections are updated twice in a five-year cycle. The schedule for these updates is linked to the timing of Australia's census.

New South Wales population growth forecast to 2041 by age groups

This dataset presents projected population by ages for 5-year periods between the years of 2011 and 2036 for the state of New South Wales (NSW). The data is presented as aggregations following the Australian Statistical Geography Standard (ASGS) 2016 Local Government Areas (LGA). Population projections provide a picture of the population as it may develop in future years. They provide an indication of the size and age-sex structure of the future population if specified assumptions about future fertility, mortality and migration are realised. Population projections are not forecasts and do not attempt to predict the impact that future government policies, changing economic circumstances or other factors (whether in Australia or overseas) might have on demographic behaviour. For more information please read the Population Projections User Guide. Please note: AURIN has spatially enabled the original data. Population numbers are rounded to the nearest 50. They should not be taken to be accurate to that level of detail. The data has been transposed to present the population age groups as distinct columns and use a compulsory filter to select the projection year. This dataset only covers LGA which have a low population.

Export DataAccess APIThe NSW population projections are a scenario based on available evidence. They are not a target or a representation of Government intent. They represent possible demographic futures based on the best assessment of how the NSW population may change over time, including population size, age profile and residential location. The projections reflect current planning frameworks and strategies in place, and the potential demographic outcomes of contemporary decisions. They represent a basis from which to plan from.Population projections provide a picture of the population as it may develop in the future. They indicate an area’s likely population size, and its age and sex profile. Understanding these changes is essential to making informed planning decisions for the State’s future. These projections are used as a common framework across NSW Government. They inform planning policy decisions around infrastructure and service delivery such as the provision of hospital beds, school classrooms, roads and public transport. Future decisions, such as infrastructure investments and land use plans, will change future population patterns including growth and distribution. These projections do not change the current visions set out in Regional Plans or affect local plans and strategies such as Local Council’s Local Strategic Planning Statements and Local Housing Strategies.MetadataContent Title2022 NSW Population Projection at 2041Content TypeOtherDescriptionNSW population, household and implied dwelling projections are produced by the Department of Planning and Environment on behalf of the NSW Government.

Data files and papers for the 2013 release of the NSW population projections.

The scheduled release of a 2013 set of NSW population projections had to change after the Australian Bureau of Statistics (ABS) announced a major review of its local area population estimates back to 1991. This is because the ABS had introduced improved methodology which is making its data more accurate.

Releasing a special set of preliminary projections in 2013 gave users of NSW population information more up-to-date data to inform decision making while a full review was finalised. The finalised set of NSW population projections was released in 2014.

These projections have since been superseded. The latest release (at November 2025) is the 2024 NSW population projections, published in November 2024. The 2024 projections are available at https://www.planning.nsw.gov.au/data-and-insights/population-projections.

Official NSW population projections are updated twice in a five-year cycle. The schedule for these updates is linked to the timing of Australia's census.
