The model Auspoll used to calculate the liveability score for each city used the data from our survey respondents who reported:
- ► The rank of each attribute (i.e. the relative importance of each attribute in making a city a good place to live); and
- ► Their level of agreement that their city exhibits each positive attribute (i.e. their level of satisfaction)
The following outlines the steps that Auspoll took in calculating the liveability score for each city – and hence the model itself:
- First, the ranks of each attribute were standardised as follows:
Standardised attribute rank = 1 + ((mean rank – attribute rank) /mean rank)
- Then, a mean attribute score was calculated for each attribute on the basis of the following satisfaction scores:
“Strongly agree” = 1
“Agree” = 0.75
“Neither agree nor disagree” = 0.5
“Disagree” = 0.25
“Strongly disagree” = 0
- A weighted attribute score was then created for each attribute by multiplying it’s standardised attribute rank by it’s mean
- The 17 weighted attribute scores were then totaled and finally multiplied by 100 to create each cities overall liveability score.
A perfect liveability score of 100 would mean that all respondents strongly agree that their city exhibits all 17 positive attributes.
For comparison, a score of 50 would imply that respondents were equally likely to agree or disagree that their city exhibits each positive attribute.
The following visually represents how this score is created:
