5 The scope of the collection consisted of all business entities operating in the Australian economy during 2017-18 and classified to:
6 Government owned or controlled Public non-financial corporations were included.
7 Micro non-employing units were excluded from the survey.
8 This section discusses frame, statistical units, coverage issues and improvements to coverage.
9 Businesses contributing to the estimates in this release are sourced from the ABS Business Register (ABSBR), which has two components as described below.
10 The ABS uses an economic statistics units model on the ABSBR to describe the characteristics of businesses and the structural relationships between related businesses. Within large and diverse business groups, the units model is used to define reporting units that can provide data to the ABS at suitable levels of detail.
11 The ABSBR sources its register information from the Australian Business Register (ABR) and uses a two population model. The two populations comprise what is called the Profiled Population and the Non-Profiled Population. The main distinction between businesses in the two populations relates to the complexity of the business structure and the degree of intervention required to reflect the business structure for statistical purposes.
12 The majority of businesses included on the ABSBR are in the Non-Profiled Population. Most of these businesses are understood to have simple structures. For these businesses, the ABS is able to use the Australian Business Number (ABN) as the basis for a statistical unit. One ABN equates to one statistical unit.
13 For a small number of businesses, the ABN unit is not suitable for ABS economic statistics purposes and the ABS maintains its own units structure through direct contact with businesses. These businesses constitute the Profiled Population. This population consists typically of large or complex groups of businesses. The statistical units model below caters for such businesses:
14 The ANZSIC based industry statistics presented in this release were compiled differently from activity statistics. Each ABN unit or TAU on the ABSBR has been classified (by the ATO and the ABS respectively) to its single predominant industry class, irrespective of any diversity of activities undertaken.
15 Some businesses engage, to a significant extent, in activities which are normally carried out by different industries. For example, a predominantly mining business may also undertake significant amounts of manufacturing. Similarly, a mining business may produce significant volumes of goods which are normally produced in different mining industries. Where a business makes a significant economic contribution to industries classified to different ANZSIC subdivisions, the ABS includes the business in the Profiled Population, and 'splits' the TAU's reported data between the industries involved. Significance is determined using total income.
16 A TAU's reported data are split if the inclusion of data relating to the secondary activity, in the statistics of the industry of the primary activity, distorts (by overstating or understating) either the primary or secondary industry statistics at the ANZSIC subdivision level by:
17 The ABS attempts to maintain a current understanding of the structure of the large, complex and diverse business groups that form the Profiled Population on the ABSBR through direct contact with those businesses. Resultant changes in their structures on the ABSBR can affect:
18 The ABS attempts to obtain data for those businesses selected for direct collection and which ceased operation during the year, but it is not possible to obtain data for all such businesses.
Improvements to coverage
19 Data in this release were adjusted to allow for lags in processing new businesses to the ABSBR, and the omission of some businesses from the register. The majority of businesses affected, and to which the adjustments apply, are small in size. As an example, the effect of these adjustments is generally 4% or less for most ANZSIC industry divisions.
20 Adjustments were made to include new businesses in the estimates for the period in which they commenced operation, rather than when they were processed to the ABSBR.
21 For more information on these adjustments, please refer to the ABS publication Information Paper: Improvements to ABS Economic Statistics, 1997 (cat. no. 1357.0).
Definition of key terms
22 Definitions for the data presented can be found in the Glossary.
23 The frame (from which the direct collect sample was selected) was stratified using information held on the ABSBR. Businesses eligible for selection in the direct collect sample were then selected from the frame using stratified random sampling techniques.
24 Businesses were only eligible for selection in the survey (the direct collect sample) if their turnover exceeded a threshold level, or the business was identified as being an employing business (based on ATO information), as at the end of the reference period.
25 Businesses which met neither of these criteria are referred to as 'micro non-employing businesses'. These businesses were not eligible for selection in the sample.
26 A sample of 10,038 businesses was selected for the directly collected part of the 2017-18 EWES. Each business was asked to provide a range of key energy and water consumption and expenditure figures via an online survey questionnaire.
Effects of rounding
27 Where figures have been rounded, discrepancies may occur between totals and the sums of the component items. Proportions, ratios and other calculated figures shown in this release have been calculated using unrounded estimates and may be different from, but more accurate than, calculations based on the rounded estimates.
28 In some cases estimates in this release may differ from those collected from other sources. These differences may be the result of sampling or non-sampling error, or may result from differences in scope, coverage, definitions, data source or methodology.
29 Estimates on energy use and electricity generation have been produced since 2008-09 from the EWES. Given each iteration of the survey has a number of differences, such as changes to the scope, data source, form design and methodology, caution should be exercised when comparing estimates over time.
30 This release does not support the calculation of an average unit price utilising the monetary estimates and physical estimates in this release. There is a broad range of price indexes published by the ABS for the purpose of measuring price change over time.
31 A select number of revised estimates for the 2014-15 reference year have been included for download to provide users with updated information. For more information on these revised estimates, please refer to the Changes since 2014-15 in this issue.
32 A range of further information is available, as described below.
33 The following ABS releases present information on energy, water and the environment:
34 In addition, the following releases present economy-wide industry data:

35 The EWES is a benchmark survey collected triennially since 2008-09. The 2017-18 results present the fourth iteration of EWES following the 2014-15, 2011-12 and 2008-09 releases. The next EWES will be conducted in respect of the 2020-21 financial year. In the interim years the Environment Indicators Survey (EIS) will be conducted in respect of the 2018-19 and 2019-20 reference periods. Data from this survey will be published in Energy Account, Australia (cat. no. 4604.0) and Water Account, Australia (cat. no. 4610.0).
36 The ABS issues a daily Release Advice on its web site which details products to be released in the week ahead.
37 Inquiries about this or other ABS releases should be made to the National Information and Referral Service on 1300 135 070.
38 ABS releases draw extensively on information provided freely by individuals, businesses, governments and other organisations. Their continued cooperation is very much appreciated; without it, the wide range of statistics published by the ABS would not be available. Information received by the ABS is treated in strict confidence as required by the Census and Statistics Act 1905.
Use of Australian Taxation Office (ATO) data in this publication
39 The results of these statistics are based, in part, on tax data supplied by the ATO to the ABS under the Income Tax Assessment Act 1936, which requires that such data are only used for statistical purposes. No individual information collected under the Census and Statistics Act 1905 is provided back to the ATO for administrative or regulatory purposes. Any discussion of data limitations or weaknesses is in the context of using the data for statistical purposes, and is not related to the ability of the data to support the ATO's core operational requirements.
40 Legislative requirements to ensure privacy and secrecy of these data have been followed. Only people authorised under the Australian Bureau of Statistics Act 1975 have been permitted to view data about any particular organisation and/or person in conducting these analyses. No information about individual taxpayers (persons) has been released to the ABS. Aggregated personal income tax data are confidentialised by the ATO before release to the ABS. In accordance with the Census and Statistics Act 1905, results have been confidentialised to ensure that they are not likely to enable identification of a particular person or organisation.
41 ABS is currently looking for ways to improve the type and format of information we provide to users, and would welcome any comments or suggestions regarding future releases of Energy Use and Electricity Generation, Australia.
42 Comments should be sent to email@example.com, or addressed to the Director, Annual Industry Statistics Business Statistics Centre, Australian Bureau of Statistics, GPO Box 2796, Melbourne, VIC 3001.
