METHODOLOGY

Sample

Conducted nationally among 1202 respondents aged 18 years and over.

Respondents were selected by means of a stratified random sample process which included:

– a quota set for each capital city and non-capital city area. Within each of these areas a quota set for each telephone area code;

– random selection of household telephone numbers drawn from current telephone listings for each area code;

– random selection of an individual in each household by a “last birthday” screening question.

Interviewing

Conducted by telephone over the period of 29 June – 1 July 2007 by fully trained and personally briefed interviewers.

To ensure the sample included those people who tend to spend a lot of time away from home, a system of call backs and appointments was incorporated.

Weighting

To reflect the population distribution, results were post-weighted to Australian Bureau of Statistics data on age, highest level of schooling completed, sex and area.
