9 This release relates to information for the quarter ended 31 December 2010
10 The response rate for the December 2010 IAS was 96.1%.
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:
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 only revised where they have a significant impact on the data released.
14 The volume of data downloaded presented should only be considered as an indicative measure of internet activity during the reference period and therefore should be used with caution.
15 Some ISPs provide proportions in lieu of actual state subscriber numbers. This data therefore have an element of estimation and should be used with caution.
16 A reporting error identified in the June quarter 2010 resulted in data being revised for the December quarter 2009 IAS. Due to a change in the computer systems used to process the IAS, the ABS is unable to revise data prior to this. Fixed wireless subscribers is the only data item significantly impacted by this revision and readers are advised to use the December quarter 2008 and June quarter 2009 figures with caution.
17 A glossary of the terms used in this release can be found under the @ a Glance pages for Innovation, Science and Technology.
