EXPLANATORY NOTES


INTRODUCTION

1 This release presents results from the Internet Activity Survey (IAS) conducted in respect of the three months ending 30 June 2009. This release contains results from all Internet Service Providers (ISPs) who operated in Australia and reported more than 1,000 active subscribers as at 30 June 2009.


SCOPE AND COVERAGE

2 The June 2009 IAS covers ISPs which operated in Australia and reported more than 1,000 active subscribers 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.

3 The source of the IAS population frame is the Telecommunications Industry Ombudsman (TIO), with which ISPs are required to register. Using this list as a basis, the ABS maintains its own confidential list of ISPs. The TIO list may contain the following organisations that are out of scope of the IAS: those that are no longer operating as ISPs including wholesalers and web hosting only; those where there is common ownership and, therefore reporting is consolidated for these ISPs on the IAS; and other types of organisations that are required to register with the TIO (e.g. Telecommunications companies).

4 The reference periods for this collection are December and June to align with international reporting of broadband statistics by the Organisation for Economic Co-operation and Development (OECD). The IAS includes information reported by all ISPs operating in Australia, with more than 1,000 active subscribers, as at 31 December and 30 June. Every three years a full census of all Australian ISPs, including those with 1,000 or less subscribers, is conducted. The last census of all ISPs was conducted in December 2008. The census is conducted as a mail-out, mail-back census of all ISPs, with ISPs who have 1,000 or less active subscribers completing a subset of questions. Their overall contribution to the December 2008 IAS was less than 1% of all subscribers with no impact on any other data released. This approach to the IAS provides frequent and timely data on key trends while keeping resource usage and provider load to acceptable levels, particularly for the smaller ISPs.

5 Connections to the internet via mobile telephones are excluded from the scope of this survey. However, mobile wireless subscriptions to the internet via a datacard or USB modem are included.


SUBSCRIBERS

6 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 30 June 2009. 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, there are single ISP subscriber accounts that provide internet access (or email addresses) for multiple people/organisations; e.g. universities.


STATISTICAL UNIT

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

8 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 or more subscribers


REFERENCE PERIOD

9 This release includes information reported by those ISPs who operated in Australia as at 30 June 2009. Figures on the volume of data downloaded relate to the three months ending 30 June 2009 as reported by ISPs operating at the end of June 2009.


RESPONSE RATE

10 The response rate for the June 2009 IAS was 93%.


IMPUTATION

11 Where data were missing or required clarification, respondents were contacted in the first instance. When necessary, missing data were imputed based on historical data collected.


RELIABILITY OF DATA

12 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.

13 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, appropriate methodology, and contact with providers to resolve anomalies. Errors in previous cycles data are not normally revised.

14 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.


GLOSSARY

15 A glossary of the terms used in this release can be found under the theme pages for Innovation, Science and Technology.
