SURVEY METHODOLOGY


General information about the 2011–12 MPHS Crime Victimisation topic, including summary results, are available in the publications Crime Victimisation, Australia, 2011–12 (cat. no. 4530.0). All summary tables, in Excel spreadsheet format, can be accessed from the Crime Victimisation Downloads page. Detailed information about the survey including scope and coverage, survey design, data collection methodology, weighting, benchmarking and estimation and the reliability of estimates can be accessed from the Crime Victimisation Explanatory Notes page.

For the 2011-12 MPHS, one person aged 15 years and over in each sampled household was selected at random (based on a computer algorithm) and asked the various MPHS topic questions in a personal interview. If the randomly selected person was aged 15–17 years, permission was sought from a parent or guardian before conducting the interview. If permission was not given, the parent or guardian was asked the crime questions on behalf of the 15–17 year old. Questions relating to sexual assault, alcohol or substances contributing to the most recent physical or face-to-face threatened assault and perceptions of the justice system were not asked of proxy respondents. Only those persons aged 18 years and over were asked questions on sexual assault. The TableBuilder file data items relating to sexual assault contains data for persons aged 18 years and over.

The TableBuilder file data items relating to alcohol or other substances contributing to the most recent physical or face-to-face threatened assault and perceptions of the justice system also contain data for persons aged 15–17 years who took part in a personal interview. This data should not be used as it is not representative of the entire population in this age group of 15–17 year olds. Care should be taken when producing tables using these data items in TableBuilder and then comparing them to publication tables, as the publication tables are about all persons aged 18 years and over.
