APPENDIX 2 FUNDAMENTAL CHANGES TO THE ANNUAL MANUFACTURING COLLECTION
2000-01 SURVEY CHANGES
1 This publication, Manufacturing Industry, Australia, 2000-01 (cat. no. 8221.0), is the first to present final manufacturing industry data based on information collected solely from manufacturing businesses (i.e. manufacturing management units). Prior to the 2000-01 survey, data were primarily collected from manufacturing establishments.
2 The move from an establishment based collection to a management unit based collection represents the initial stage in a fundamental shift (see paragraph 12 below) in the statistical unit from which data are primarily being sought and published (for the definitions of management units and establishments, see the Glossary). As such, the publication of data for manufacturing management units represents a break in series from the data previously published for manufacturing establishments.
3 Although, prior to 2000-01, the annual manufacturing collection has primarily collected data from manufacturing establishments, it has also collected data from a relatively small sample of manufacturing management units. This annual sample of approximately 5,000 manufacturing businesses has provided data on employment, wages and salaries, sales and service income, purchases, inventories, capital expenditure and detailed information required to derive OPBT. Information from this sample of manufacturing management units has generally been available at the Australian level for industry groups and selected industry classes on request and for a charge.
4 This publication draws on summary of operations data collected previously from manufacturing management units to provide a time series, at the industry subdivision level, from 1995-96. It also contains all of the previously published tables but now on a management unit basis. The approximately 9,500 businesses included provide a sample large enough to support manufacturing management unit based data at the industry class level for Australia.
5 Appendix 3 contains tables for 1999-2000 showing manufacturing establishment data and manufacturing management unit data for employment, wages and salaries, turnover, sales and service income and IVA. These tables are designed to provide a bridge between the previous establishment based series and the new manufacturing management unit based series.
6 Management units do not normally apportion activity by state and territory, as was the case for establishments. However, in order to ensure that reliable data by state and territory are available, approximately 400 businesses (i.e. those that have significant operations in more than one state and/or territory) have been requested to provide additional details on employment, wages and salaries and sales of goods and services for each state and/or territory in which they operate. This information was used to synthesise on a pro-rata basis all other data reported for the whole business to each state and/or territory in which they operate. This enabled the production of state/territory data for employment, wages and salaries, sales and service income and IVA at the industry subdivision level. However, it is not possible to produce data by employment size or data relating to exported production.
7 State publications, Manufacturing Industry, [state], (cat. nos 8221.1-8221.6), will not be produced for 2000-01.
8 Regional or sub-state data are not available from the 2000-01 manufacturing survey. This is a direct result of moving to a manufacturing management unit based collection for 2000-01; see paragraphs 1 and 2.
2001-02 SURVEY CHANGES
9 In April 2000, the ABS released an information paper, ABS Statistics and The New Tax System (cat. no. 1358.0), which foreshadowed changes in the statistical infrastructure supporting the compilation of ABS economic series. The changes will allow better use of data available from the taxation system to improve efficiency, coverage and sample design.
10 This publication presents the last release of estimates from the annual manufacturing collection compiled using the old infrastructure.
11 In the 2001-02 suite of publications, estimates for the latest period will be compiled on the new basis. To facilitate comparisons over time, the next release of this publication will include estimates of the impact on statistical series of the infrastructure changes.
12 An information paper, Improvements in ABS Economic Statistics [Arising from The New Tax System] (cat. no. 1372.0), was released on 6 May 2002. That paper described the changes in more detail and provided information about the treatment of statistical impacts of the changes across ABS economic series.
13 Every fifth year, the annual ABS manufacturing collection is expanded from a survey to a census. It is proposed to retain this cycle with the shift to the new statistical infrastructure. Therefore, the next manufacturing census will be conducted in respect of 2001-02.
14 Regional or sub-state data will be produced for 2001-02, and it is proposed to produce state publications for 2001-02. Further investigations will be undertaken to decide if it is possible to produce some sub-state estimates insurvey collection years from 2002-03.
