Evaluation of National Skin Cancer Awareness Campaign - 2008-09

3.2 Sample characteristics

prev page| TOC |next page

The following figures show the sample characteristics of the unweighted sample.

Figure 3.2.1 shows that the sample was somewhat unbalanced in terms of gender for each target audience, particularly in the earlier waves. The analyses were weighted to correct for the gender imbalance⁴.

Figure 3.2.2 shows the distribution of the five survey samples, across metropolitan and non-metropolitan areas. In the pre-campaign survey, there was an overrepresentation of people living in Melbourne, and an under-representation of those from Sydney. Accordingly, the data have been weighted to correct for this imbalance, and to reflect the distribution of the Australian population.

The income distribution of the sample is shown in Figure 3.2.3. A large proportion of participants were unable to estimate their household’s income, reflecting the fact that around half of the sample was comprised of 14-17 year olds.

Those aged 16 years and above were asked about their employment status. The results are shown in Figure 3.2.4.

Figure 3.2.5 shows that just under half of those in the sample described themselves as very fair or fair.
