EXPLANATORY NOTES


INTRODUCTION

1 This publication presents results from the Internet Activity Survey (IAS) conducted in respect of the three months ending 31 March 2007. These results represent all Internet Service Providers (ISPs) operating in Australia with over 10,000 active subscribers as at 31 March 2007.



SCOPE AND COVERAGE

2 The IAS covers 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, Internet cafes and hot-spots 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 Every September quarter from 2006, the IAS will be conducted as a mail-out, mail-back census of all ISPs, with ISPs with a 1,000 or less subscribers completing a subset of questions. Every March quarter from 2007 a subset of the population, those ISPs with more than 10,000 subscribers, will be surveyed to obtain frequent data on key patterns.



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 ending 31 March 2007. 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 multiple people/organisations.



STATISTICAL UNIT

5 The unit for which statistics are reported in the IAS is the legal entity providing Internet access.


6 ISPs in the IAS 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 ISP1 - 100 subscribers
Small ISP101 - 1,000 subscribers
Medium ISP1,001 - 10,000 subscribers
Large ISP10,001 - 100,000 subscribers
Very large ISP100,001 + subscribers


REFERENCE PERIOD

7 This publication includes information reported by all ISPs with over 10,000 active subscribers which were operating in Australia at 31 March 2007. Figures on the volume of data downloaded relate to the three months ending 31 March 2007 as reported by ISPs operating at the end of March 2007.



RELIABILITY OF DATA

8 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.

9 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.


10 Download data presented should only be considered as an indicative measure of Internet activity during the reference period and therefore should be used with caution.



ACKNOWLEDGMENT

11 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.
