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.

• The data has been transposed to present the population age groups as distinct columns and use a compulsory filter to select the projection year.

• Population numbers are rounded to the nearest 50. They should not be taken to be accurate to that level of detail.

This dataset presents projected population following the three projection series - the main projection, a high and a low projection series 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).

The various projection series show the impact on the NSW population when the assumed levels of births, deaths and migration are changed.

This dataset presents projected number of households by type 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).

Household projections show the number of households that would form if demographic trends continue and if assumptions about living arrangements are realised over the projection period. A household is two or more people who share a dwelling (house, apartment, townhouse, caravan, etc.) and share food and cooking facilities, and other essentials. Household projections show the future number and type of households living in private dwellings. Private dwellings are self-contained accommodation such as houses, apartments, mobile homes or other substantial structures. It does not include accommodation such as boarding houses, nursing homes or prisons.

The household projections also include the implied dwelling demand for those households. This is the likely number of private dwellings needed to accommodate future population-driven demand.

For more information please read the Household Projections User Guide.

• AURIN has spatially enabled the original data.

• Household and dwelling numbers are rounded to the nearest 50. They should not be taken to be accurate to that level of detail.

Treasury media release 2009

In June 2022, it was estimated that around 7.3 percent of Australians were aged between 25 and 29, and the same applied to people aged between 30 and 34. All in all, about 55 percent of Australia’s population was aged 35 years or older as of June 2022. At the same time, the age distribution of the country also shows that the share of children under 14 years old was still higher than that of people over 65 years old. A breakdown of Australia’s population growth Australia is the sixth-largest country in the world, yet with a population of around 26 million inhabitants, it is only sparsely populated. Since the 1970s, the population growth of Australia has remained fairly constant. While there was a slight rise in the Australian death rate in 2022, the birth rate of the country decreased after a slight rise in the previous year. The fact that the birth rate is almost double the size of its death rate gives the country one of the highest natural population growth rates of any high-income country.
National distribution of the population Australia’s population is expected to surpass 28 million people by 2028. The majority of its inhabitants live in the major cities. The most populated states are New South Wales, Victoria, and Queensland. Together, they account for over 75 percent of the population in Australia.
