INTRODUCTION

1 This publication presents results from the Internet Activity Survey (IAS) conducted in respect of the three months ending 30 September 2004.



CENSUS SCOPE AND METHODOLOGY

2 The IAS is a census that covers all identified Internet Service Providers (ISPs) providing Internet access across Australia. The scope of the IAS is all Australian based ISPs operating at the end of the reference period. ISPs are defined as businesses that supply Internet connectivity and access services to individuals, households, businesses, government and other organisations. Libraries, Internet kiosks and Internet cafes which provide Internet access on a casual basis are excluded from the census. The primary source of the IAS population frame is the Telecommunications Industry Ombudsman (TIO) with which ISPs are required to register. The TIO list is supplemented with ISPs identified from other sources such as Internet association membership lists and industry media.


3 The IAS is conducted as a mail-out, mail-back census.



SUBSCRIBERS

4 Active subscribers are defined as subscribers having accounts with ISPs who have accessed the Internet or paid for access to the Internet during the three months of the reference period. Counts of subscribers are not the same as counts of people/organisations with Internet access because subscribers may have accounts with more than one ISP. Conversely, a single ISP subscriber account may provide Internet access (or email addresses) for several people/organisations.



STATISTICAL UNIT

5 The unit for which statistics were reported in the census was the legal entity providing Internet access.


6 ISPs in this census have been classified by size according to the number of subscribers ISPs reported for at the end of the reference period. The size categories are defined as follows:

      Very small ISP 1 - 100 subscribers
      Small ISP 101 - 1,000 subscribers
      Medium ISP 1,001 - 10,000 subscribers
      Large ISP 10,001 - 100,000 subscribers
      Very large ISP 100,001 + subscribers


REFERENCE PERIOD

7 At present, the IAS is conducted biannually and the reference quarters are March and September. This equates to the end of March and September for most data items collected and the three months ended March and September for volume of data downloaded. This publication includes information reported by ISPs which were operating in Australia at the end of the reference quarter. Figures on the volume of data downloaded relate to data downloaded during the three months of the reference quarter as reported by ISPs still in operation at the end of the reference quarter. No attempt is made to collect volume of data downloaded from ISPs who ceased operation during the three months to the end of the reference quarter.


8 Following the March quarter 2005 collection, the frequency of the IAS will reduce from biannual to annual.



RELIABILITY OF DATA

9 As the IAS does not have a sample component, the data are not subject to sampling variability. However, other inaccuracies, collectively referred to as non-sampling errors, may affect the data. These non-sampling errors may arise from a number of sources, including:

  • errors in the reporting of data by respondents;
  • errors in capturing or processing of data;
  • estimation for missing or misreported data; and
  • definition and classification errors.

10 Every effort has been made to reduce non-sampling error to a minimum by careful design and testing of questionnaires, efficient operating procedures and systems, and appropriate methodology.


11 Estimates for data at the state/territory level are derived from the data provided for POPs (Points of Presence or servers). In recent cycles, changing access technologies, infrastructure and operational arrangements have been impacting on the quality of the data at the POP level. As a result, data presented at the state/territory level should be considered only indicative measures of Internet activity at the reference date.


12 The same issues related to the quality of POP data have had a more significant impact at the Statistical Division level. These data cannot be adequately quality assured and could present misleading indicators of regional activity and usage. These data are no longer available for release.



ACKNOWLEDGMENT

13 ABS publications 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.


14 In particular, the ABS acknowledges the assistance of the TIO in providing regular lists of registered ISPs.
