As of June 2023, there were approximately 8.33 million residents in the New South Wales region in Australia. In comparison, there were around 252 thousand residents in the Northern Territory region.

As of December 2023, the proportion of the Australian population that lived in New South Wales amounted to 31.3 percent. The Northern Territory had the least number of residents in the country, with less than one percent of the population residing there.

Estimated resident population (ERPs) is the official measure of the Australian population, published quarterly by the ABS. This dataset contains quarterly ERP by age, at state/territory and Australia level.

According to the 2016 Australian census, 33.6 percent of Australia's overseas born population lived in the state of New South Wales. Tasmania and the Northern Territory were home to the smallest proportion of overseas-born people living in Australia, with a combined share of less than two percent.

The estimated resident population (ERP) is the official measure of the Australian population. This dataset contains annual ERP by country of birth, age and sex at the Australia level. At the state/territory level it is available for Census years only.

Population data was collected as part of national census’ in 1991, 1996, 2001, 2006 and 2011. Data presented is the total population for all collection districts by place of enumeration. District Boundaries differed for each census and therefore were re-projected onto the 2011 population mesh blocks to standardise the spatial extent of the reporting areas. Given the focus of this project, population data was clipped by a 50km coastal buffer. Note: population data for census’ 1991 – 1996 - 2001 was purchased by NESP and is made publically available through by NESP Note: population data for 2006 and 2011 was downloaded through the ABS webportal. http://www.abs.gov.au/websitedbs/censushome.nsf/home/tablebuilder?opendocument&navpos=240 Note. 2006 Census district boundaries were downloaded from the ABS website http://www.abs.gov.au/AUSSTATS/abs@.nsf/Lookup/2919.0.55.001Main+Features1Aug 2006?OpenDocument and 2011 population mesh blocks http://www.abs.gov.au/ausstats/abs@.nsf/mf/1270.0.55.001 This data contains geographical information in shape files that represent the population density in Australia, from 1991 to 2011. The data contains the summary polygon, state_code, cd_code19, 91_pop_dat (population count), area and density (in persons per km^2). For other data sets the count will be 96_pop_dat, 2001_pop_dat, 2006_pop_dat and 2011_pop_dat.

As at June 30, 2016 there were 2,895,476 households in the state of New South Wales in Australia, the highest number of households of any other state or territory. It is expected that by 2041 this number will have increased to just over four million households in the state of NSW.

Contains projections (based on different assumptions of future fertility, mortality and migration) of the resident population of Australia, the states and territories, capital cities and balance of states, by age and sex for the base year to 2101 (for Australia) and for the base year to 2061 (for the states and territories, capital cities and balances of states). Also includes summary measures such as percentages of population in selected age groups and median ages as well as detailed notes on the assumptions used.

This dataset presents the estimates of the internal and overseas migration statistics of Australia by age by Statistical Area Level 2 (SA2) following the 2016 Australian Statistical Geography Standard (ASGS). The dataset spans from the 2016-17 financial year up to the 2019-20 financial year.

Overseas migration is the movement of people from overseas to Australia's sub-state areas and vice-versa. It cannot be directly measured and is estimated by breaking down overseas migrant arrivals and departures at the state level to sub-state areas, using information from the most recent Census. The state-level overseas migration data is sourced from Department of Home Affairs processing systems, visa information, and incoming passenger cards, and is published in National, state and territory population.

Internal migration is the movement of people across a specified boundary within Australia involving a change in place of usual residence. It cannot be directly measured and is instead estimated using administrative data. The movement of people between and within Australia's states and territories cannot be directly measured and is estimated using administrative data. Internal migration is estimated based on a combination of Census data (usual address one year ago), Medicare change of address data (provided by Services Australia), and Department of Defence records (for military personnel only).

The Medicare source data is assigned to a state or territory and GCCSA for a person's departure and arrival locations, based on the postcodes of their residential addresses as registered with Medicare. Postcodes are assigned wholly to a state/territory and GCCSA based on best fit. Where a postcode is split across areas, it is assigned to the area that contains the majority of that postcode's population.

ERP for sub-state regions (including SA2s and LGAs) is published annually, with a reference date of 30 June. ERP is the official measure of the Australian population, based on the concept of usual residence. It refers to all people, regardless of nationality, citizenship or legal status, who usually live in Australia, with the exception of foreign diplomatic personnel and their families. Note, years 2012-2016 describe preliminary rebased (PR) data. For more information about PR refer to the dataset's Explanatory Notes. This dataset has been compiled using Census data, mathematical models and a range of indicator data. Current indicators include building approvals, Medicare enrolments (provided by the Department of Human Services) and electoral enrolments (provided by the Australian Electoral Commission).

The share of the Aboriginal and Torres Strait Islander population in Australia in 2019 was highest in New South Wales with around 33 percent of the indigenous population in Australia living there. Comparatively, the Australian Capital Territory accounted for only one percent of the country's indigenous population in that year.

At the 2021 Australian census, 278,043 people in New South Wales were Aboriginal or Torres Strait Islander. New South Wales is Australia’s most populated state, also housing Australia’s largest city, Sydney. By comparison, Australia’s second largest state, Victoria, was home to around 66 thousand Aboriginal and Torres Strait Islander people.

Aboriginal and Torres Strait Islander peoples

There are around 800,000 Aboriginal and Torres Strait Islander people in Australia, which represents just over three percent of the Australian population. Indigenous people are often referred to as Australia's first people or the traditional custodians of the land in recognition of their ancestors inhabiting Australia more than 60,000 years ago. Australia's Indigenous peoples are represented by two distinct groups. Aboriginal people come from the Australian mainland. Torres Strait Islander people inhabit the group of Islands between the northern tip of Queensland and Papua New Guinea and represent less than 40,000 people.

Closing the gap

Aboriginal and Torres Strait Islander peoples experience significantly poorer health and wellbeing outcomes when compared to their non-Indigenous Australian counterparts. The average life expectancy of Indigenous Australians is around eight years shorter than that of the non-Indigenous population. In education, Indigenous Australians are also underrepresented, but attendance rates are improving and in 2019, full-time Aboriginal and Torres Strait Islander students numbered well over 200,000 people.
