QUALITY DECLARATION - SUMMARY
The statistics presented have been derived using a combination of directly collected data from the annual Economic Activity Survey (EAS), conducted by the Australian Bureau of Statistics (ABS), and Business Activity Statement (BAS) data provided by businesses to the Australian Taxation Office (ATO). The survey data were collected under the authority of the Census and Statistics Act 1905. The Income Tax Assessment Act 1936 provides for the ATO to pass information to the Australian Statistician for the purposes of the Census and Statistics Act 1905.
The data illustrate the size, structure and performance of Australian industry during the 2007-08 financial year and, to a lesser extent, over time. The estimates are also used in the compilation of Australian National Accounts aggregates, produced by the ABS.
The scope of the estimates in this release consists of all businesses on the ABS Business Register, except for:
Government-owned or controlled Public Trading Enterprises are included.
The frame used for the survey of Australian industry, like most ABS economic surveys, was taken from the ABS Business Register. The ABS Business Register is updated monthly to take account of new businesses and businesses which have ceased operating.
The period covered by the estimates is, in general, the twelve months ended 30 June. Where businesses are unable to supply information on this basis, an accounting period for which data can be provided is used for data other than that relating to employment. Such businesses make a substantial contribution to some of the estimates presented in this release. As a result, the estimates can reflect trading conditions that prevailed in periods outside the twelve months ended June in the relevant year.
A component of the sample survey was not specifically designed to produce state estimates. For these units, state data was apportioned using BAS data obtained from the ATO. For the remainder of sampled units, directly collected data was used. Each sampled business was asked to supply key details of their operations by state and territory, enabling the production of some state/territory estimates.
The survey is conducted annually. Forms are despatched in August. The business taxation data are received in November following the end of the reference period. The ABS aims to publish estimates from its annual business survey program within twelve months of the end of the reference period.
The ABS aims to produce high quality data from its industry collections while minimising the reporting burden on businesses. To achieve this, extensive effort is put into survey and questionnaire design, collection procedures and processing. The 2007-08 survey used generalised regression estimation. Generalised regression estimation is a form of ratio estimation which makes use of auxiliary data items which are strongly correlated with key data items directly collected by the ABS from businesses. The auxiliary variables used in this survey were turnover and wages from data sourced from the Australian Taxation Office (ATO). Use of this methodology allowed high quality statistics to be produced from a small sample of 15,687 businesses.
Sampling error occurs when a sample, rather than the entire population, is surveyed. It reflects the difference between estimates based on a sample and those that would have been obtained had a census been conducted. One measure of this difference is the standard error. There are about two chances in three that a sample estimate will differ by less than one standard error from the figure that would have been obtained if all businesses had been included in the survey, and about nineteen chances in twenty that the difference will be less than two standard errors.
The ABS has been conducting annual surveys of Australian industry since 1990-91.
Estimates from the survey of Australian industry are available as original series only, and are not seasonally or trend adjusted.
Data from the 2007-08 survey of Australian industry are available in a variety of formats. The formats available free of charge on the ABS website are:
