Australian Bureau of Statistics

The Australian Bureau of Statistics (ABS) is an Australian Government agency that collects and analyses statistics on economic, population, environmental, and social issues to advise the Australian Government.

The bureau's function originated in the Commonwealth Bureau of Census and Statistics, established in 1905, four years after Federation of Australia; it took on its present name in 1975. The ABS conducts Australia's Census of Population and Housing every five years and publishes its findings online.

History
Efforts to count the population of Australia started in 1795 with "musters" that involved physically gathering a community to be counted, a practice that continued until 1825. The first colonial censuses were conducted in New South Wales in 1828; in Tasmania in 1841; South Australia in 1844; Western Australia in 1848; and Victoria in 1854. Each colony continued to collect statistics separately despite attempts to coordinate collections through an annual Conference of Statisticians. The first simultaneous census across all the Australian colonies occurred in 1881. A national statistical office was subsequently proposed to develop comparable statistics.

The Commonwealth Bureau of Census and Statistics (CBCS) was established under the Census and Statistics Act 1905. Sir George Handley Knibbs was appointed as the first Commonwealth Statistician. The bureau was located in Melbourne – at that time the temporary seat of federal government – attached to the Department of Home Affairs. In 1928, the bureau relocated to Canberra, where in 1932 it was subsumed within the Department of the Treasury.

The first national census, which deployed about 7300 collectors, occurred in 1911. Although coordination and data sharing were facilitated by CBCS, each state in Australia initially had its own statistical office and worked with the CBCS to produce national data. Some states faced challenges in providing a satisfactory statistical service through their own offices, resulting in mergers with the CBCS. The Tasmanian Statistical Office was transferred to the CBCS in 1924, and the New South Wales Bureau of Statistics amalgamated into it in 1957. The final unification of all state statistical offices with the CBCS occurred in the late 1950s under the guidance of Sir Stanley Carver, who was the New South Wales Statistician acting as the Commonwealth Statistician.

In 1974, the CBCS was abolished and replaced by the Australian Bureau of Statistics (ABS). The Australian Bureau of Statistics Act 1975 established the ABS as a statutory authority headed by the Australian Statistician, who reported to the federal Treasurer.

In 2015, the Australian Government announced a $250 million five-year investment in the ABS to modernise its systems and processes.

Census of population and housing
Once every 5 years, the ABS conducts the Australian Census of Population and Housing as stipulated under federal law in the Constitution of Australia. The most recent was conducted on 10 August 2021. Statistics from the census were published on the ABS website in June 2022.

The census aims to accurately measure the population, number of dwellings in Australia, and a range of their key characteristics. Census data is used for defining electoral boundaries, planning infrastructure, establishing community services, and formulating public policy.

2016 census
In 2016, the ABS conducted its census largely online through its website and logins rather than through paper forms. The bureau took the form offline for 43 hours from 8:09 pm on 9 August until 2:29 pm on 11 August. On 10 August, the Australian Statistician, David Kalisch, stated that the website was closed after denial-of-service attacks from an overseas source targeted the online form; "the first three were successfully repelled and the fourth one caused the difficulty that then led us to bring the system down as a precaution". A comprehensive review by Alastair MacGibbon, Special Adviser to the Prime Minister on Cyber Security, tabled in October, concluded that five distributed denial-of-service attacks – in which incoming traffic from many different sources "floods" the site – had occurred. They had been much smaller than attacks experienced by other Australian Government websites and the preventable outages had resulted from a failed geoblocking strategy, compounded by a hardware failure when the contractor, IBM, attempted to reboot the system after the fourth attack. There was no indication that the census data was insecure or was compromised. Many recommendations of the review included that the ABS should strengthen its approach to managing the performance of outsourced ICT suppliers and that the ABS "should draw upon the lessons it takes from the Census experience to help to guide and to advocate for the cultural change path it is following".

A Senate inquiry was held into the 2016 census, reporting in November and making 16 recommendations including externally conducted privacy impact assessments, engagement with the non-government sector, reporting breaches of census-related data, open tendering, and stability in funding the bureau. An independent panel was also established by the Australian Statistician to help to ensure the quality of the 2016 census.

2021 census
The 2021 census was conducted during the height of the global Covid-19 pandemic. In obtaining data from 10,852,208 dwellings, it exceeded the ABS target. The dwelling response rate was 96.1%, an increase from 95.1% in 2016.

Publications
The ABS publishes monthly and quarterly economic information spanning interest rates, property prices, employment, the value of the Australian dollar, and commodity prices. Publications include things such as: the Key Economic Indicators, Consumer Price Index, Australian National Accounts, Average Weekly Earnings, and Labour Force.

Other major publications
Outside the main economic indicators, the ABS has several other major publications covering topics including:
 * Health: The 2011–12 Australian Health Survey was a survey on health and wellbeing conducted in Australia. The survey included a biomedical component with respondents having the option of providing biomedical samples such as blood and urine for testing. This allowed the survey to capture detailed health information about health conditions in the community. A secondary component of the Australian Health Survey asked respondents to keep a food diary, which was used to obtain a view of the nutritional intake and dietary preferences of the nation.
 * Crime: The ABS publishes crime statistics such as individual releases covering offenders, victims of crime, the corrections system and prisons. The Australian crime rate statistic for 2021 was 0.74, a 13.51% decline from 2020.
 * Demography: The ABS publishes many demographic releases including data on population, population growth and projections, interstate and overseas migration, births, deaths and overseas arrivals and departures.
 * Aboriginal and Torres Strait Islander statistics: The National Aboriginal and Torres Strait Islander Social Survey (NATSISS) collects information on the social situation of Indigenous Australians, including data on health, education, culture, and labour force participation. The ABS also collects data related to Aboriginal and Torres Strait Islanders through the Australian Health Survey as well as in many other regular publications in the areas of demography, education, employment, and more.
 * Education: The major education publications are Childhood Education and Care, Schools, and Education and Work. They look at all aspects of education in Australia from preschool up to undergraduate and postgraduate study.
 * Environment: The ABS has publications on environmental topics covering energy and water use, conservation activities undertaken by households, land management, farming, and more.
 * Research and Innovation: The ABS has been undertaking surveys to collect estimates from Australian organisations regarding expenditure on and human resources devoted to research and development (R&D) in Australia since 1978. The results allow the nature and distribution of Australia's R&D activity to be monitored by government policy analysts and advisers to government, businesses, and economists.

In August 2017, the Treasurer issued a directive to the ABS to undertake a statistical collection into the views of Australians on the electoral roll about same-sex marriage. This is now referred to as the Australian Marriage Law Postal Survey.

The ABS previously published the Yearbook Australia, from 1908 to 2012 under various ISSNs and titles (Commonwealth yearbook, Official yearbook of the Commonwealth of Australia).

The ABS publishes an annual report with a detailed description of the bureau's activities during the preceding year, accounting for its use of public resources and performance against planned outcomes.

International engagement
The ABS engages in international and regional statistical forums including the United Nations Statistical Commission (UNSC), the Organisation for Economic Cooperation and Development (OECD) Committee on Statistics and Statistical Policy (CSSP), and the United Nations Economic Commission for Europe (UNECE) Conference for European Statisticians (CES).

The ABS has a partnership with DFAT to deliver statistical and institutional capability building programs for the Indo-Pacific region, both in-country and by hosting development visits. The ABS has also hosted international development and study visits from countries including China, Japan, Canada, Korea, and Nepal.

Australian Statistician
Since 1975, the head of the ABS has been known as the "Australian Statistician". The title has been previously known as the "Commonwealth Statistician".

The incumbent since 11 December 2019 is David Gruen. Previous incumbents have included David Kalisch and Brian Pink. Pink retired in January 2014. Ian Ewing acted in the role from 13 January to 14 February 2014, and Jonathan Palmer acted from 17 February to 12 December 2014.
