POINTS OF PRESENCE
8 The number of POPs relates to the sum of POPs made available by individual ISPs. This may be more than the number of physical POPs due to the sharing of POPs between ISPs.
9 Data contained in this publication relate to ISPs which were operating in Australia at the end of the reference quarter. Counts of ISPs reflect only those businesses operating at the end of the reference quarter. Volume of data downloaded figures relate to data downloaded during the three months of the reference quarter.
RELIABILITY OF DATA
10 As the census does not have a sample component, the data are not subject to sampling variability. However, other inaccuracies collectively referred to as non-sampling error may affect the data. These non-sampling errors may arise from a number of sources, including:
11 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.
12 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.
13 In particular, the ABS acknowledges the assistance of the TIO in providing regular lists of registered ISPs.
