METHODOLOGY & FUNDING
Conducted nationally in Australia by Newspoll Limited
Respondents: 1,201 (2008), 1,100 (2010), 1,219 (2012), 1,204 (2014); Australian citizens and permanent residents aged 18 years and over.
Respondents were selected via a stratified random sample process which included:
- a quota being set for each capital city and non-capital city area, and within each of these areas, a quota being set for groups of statistical divisions or subdivisions;
- random selection of household telephone numbers using random digit dialling (RDD);
- random selection of an individual in each household by a "last birthday" screening question.
- Conducted by telephone over the period of 1-8 May 2008, 1-14 March 2010, 24 September–9 October 2012, 19 August-2 September 2014
- Conducted 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.
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;
- federal voting intention (using the previous two Newspoll voting intention surveys) (2008, 2014).
Percentages shown are based on these weighted figures.
