Due to the difference in the scope of previous surveys, household use of information technology (HUIT) data from the 2005-06 MPHS onwards (the scope of which is persons aged 15 years and over) are not directly comparable with data from previous years, which was limited to persons aged 18 years and over.
HUIT data for 2003 were obtained from the SDAC, where person level data only relates to those with a disability aged 15 years or over. Data are not comparable with results from MPHS which covers all persons 15 years or over. However, SDAC and MPHS data are comparable at the household level.
The 2002 HUIT data were obtained from the GSS using a face-to-face randomly selected person methodology. MPHS questions were asked using a telephone interview. The ABS has taken reasonable steps during the survey development process to ensure that this change in collection methodology does not affect the quality of the data, however, a small impact on responses for the more complex questions cannot be ruled out.
The HUIT publication contains detailed Explanatory Notes, Technical Notes and a Glossary that provide further information on the terminology, classifications and other technical aspects associated with these statistics. Detailed Explanatory Notes are also provided for the 2006 TUS.
