If you would like to know more about statistical literacy, check out: What is statistical literacy and why is it important to be statistically literate? as featured in Tasmanian State and Regional Indicators, Mar 2009 (cat. no. 1307.6).
Population estimates are one of the major outputs of any national statistical office. While population can be simply defined, such as the 'total number of persons living in an area', the concepts associated with its measurement are usually complex. In Australia, there are several legislative requirements for the production of population estimates. The key population measure is estimated resident population (ERP), which is defined in terms of the number of people who usually live within Australia and its states and territories. ERP is used in determining the number of seats each state/territory has in the House of Representatives and as the relative distributional basis for Commonwealth grants to states/territories and local government authorities. It is also critical input for a wide range of planning and policy decisions.
The five-yearly Census of Population and Housing is the basis for ERP. Between Censuses, ERP is calculated by aging the base population and then adjusting for subsequent components (i.e. births, deaths, overseas migration and interstate migration) of population growth. This method, known as the 'cohort component method', is used to produce state level population estimates on a quarterly basis.
Below state level, ERP is widely used by all levels of government, as well as business and community. Estimates are produced on an annual basis for statistical local areas (SLAs), which build up to higher levels of geography such as local government areas and statistical divisions. There are no reliable sources of migration data at the SLA level, making it very difficult to estimate SLA population between Censuses using the cohort component method. Instead, mathematical models, which establish relationships between changes in population and changes in population indicator data between the two most recent Censuses for groups of SLAs, are used. Post-censal changes in these indicators are used to estimate changes in the population of SLAs for the years following the most recent Census.
More detail about how the ABS derives ERP, and the role of the Victorian regional office in producing these estimates, is in a feature article 'Measuring Victoria's Population' published in the March quarter 2009 issue of State and Regional Indicators, Victoria (cat. no. 1367.2).
ABS Community Services Survey 2008-09
ABS is planning to conduct a survey of selected Community Service industries in August 2009, and will seek data in respect of the 2008-09 financial year. The survey was last conducted in respect of 1999-00, and data released in Community Services, Australia, 1999-2000 (cat. no. 8696.0).
Results from the 2008-09 survey will provide key financial and activity measures on community services in Australia, and be used by government and industry analysts to address policy issues relating to the community services sector. Data from this survey are expected to be available in mid-2010.
The survey questionnaire will be despatched in August 2009 to a representative sample of organisations in both the government and non-government sectors (including for-profit and not-for-profit organisations) involved in the provision of community services. These services include: child care; aged accommodation, and other residential and non-residential care; personal and social support; financial and material assistance; job placement and support for persons with disabilities; and group advocacy services.
Cooperation of public and private sector organisations in providing information for this survey is essential for ABS to produce accurate and timely results, and maximise the relevance of these statistics. ABS greatly appreciates the time and effort required to make an effective contribution to this survey.

Energy, Water and Environment Survey 2008-09
ABS is pleased to advise that we have secured financial support for the Energy, Water and Environment Survey (previously referred to as the Environment Management Survey) to proceed for the 2008-09 year. ABS received valuable feedback from many interested parties and have carefully considered their needs and priorities in developing the survey. In August 2009, approximately 15,000 Australian businesses will receive an Energy, Water and Environment survey form. Survey results will be publicly available on the ABS website from May 2010, and used to inform government, industry and the research community on issues relating to energy and water use and management, environmental management and innovation by Australian businesses.
Once again, ABS appreciate the input and effort by many to get to this point. For further information contact Sarah Coleman ph (02) 6252 7715 or email <email@example.com>. Victorian Statistics Advisory Forum of 24 June 2009

Reviewing Statistics Victoria and State and Regional Indicators, Victoria
The Victorian Statistical Coordination Branch is reviewing the dissemination strategy for two ABS web publications: Statistics Victoria, Newsletter (cat. no. 1100.2) and State and Regional Indicators, Victoria (cat. no. 1367.2). Over the next six months, the review will consider the purpose, intended audience, content, scope, structure, format, delivery mediums, method of release, timing, production processes and resources for the two publications. It will explore options and propose new solutions for the dissemination of state and regional statistics for Victoria that are more cost effective to produce, and more relevant to clients. The review will consult with users and take advantage of the changed ABS web environment to address user requirements. During the review, State and Regional Indicators, Victoria (cat. no. 1367.2) will continue in a quarterly web-based e-magazine format.
