Quality of life
Overall quality of life refers to a person’s evaluation of their own circumstances and experience of life, which is shaped by their cultural, social and environmental context . Overall quality of life is generally accepted to be more nuanced and complex than other health concepts such as health status, lifestyle, or life satisfaction . Overall quality of life has been measured in the Canterbury Wellbeing Survey since 2012 .
This indicator presents the proportion of those 18 years and over indicating that their overall quality of life was good or extremely good, as reported in the Canterbury Wellbeing Survey.
The figure shows an overall increase in self-reported quality of life (proportion of those rating their quality of life as good or extremely good) for greater Christchurch, between 2012 (73.5%) and 2022 (81.6%). The 2022 result is not statistically significantly different from the 2020 result, although, taken together, the 2020/2022 results show the first statistically significant decline in self-reported quality of life (compared with 2019) since the start of the time series in 2012. The general pattern of decline between 2019 and 2022 follows a period of incremental gains over the preceding six years.
The figure shows that levels of overall quality of life (proportion of those rating their quality of life as good or extremely good) have generally been higher for European respondents, compared with Māori and Pacific/Asian/Indian respondents. This difference has been statistically significant for much of the time-series presented. In 2022, the proportion of European respondents rating their quality of life as good or extremely good remains statistically significantly higher than that for Pacific/Asian/Indian respondents (European, 83.0% compared with Pacific/Asian/Indian, 72.5%) and for Māori respondents, 75.8%). While there is some variability in the results for Māori (due to smaller absolute numbers in the survey sample) there appears to be an overall pattern of convergence of the proportion for Māori and European respondents over the last eight years (less so for Pacific/Asian/Indian respondents).
The figure shows a pattern of converging overall quality of life (proportion of those rating their quality of life as good or extremely good) for the age groups over the time-series. While there have been some statistically significant differences between young people and the older age groups, at some earlier time-points, there have been no statistically significant differences between any age groups since late 2016.
The figure shows a clear positive relationship between income and overall quality of life, with the proportion of those rating their overall quality of life as good or extremely good increasing with increasing annual household income. The differences between the four income groups shown in the figure have been statistically significant at most time-points across the time-series. In 2022, almost all (91.3%) of those respondents from the $100,000+ income group rated their quality of life as good or extremely good, compared with 56.4 percent of those from the <$30,000 income group (a large and statistically significant difference). The year-to-year differences in overall quality of life for the period 2019 to 2022 are generally not statistically significant, except for the $100,000+ group (down from 94.9% in 2020 to 91.3% in 2022). Additionally, the lowest income group’s quality of life appears to have declined notably (for the <$30,000 group, 70.9% 2019 to 56.4% 2022).
The figure shows lower levels of overall quality of life (proportion of those rating their quality of life as good or extremely good) for respondents with a long-term health condition or disability (both for the under- and over-65 groups), compared with those without a long-term health condition or disability, from 2012 to 2022. The substantial differences between the without a long-term health condition or disability group and each of the long-term health condition or disability groups have been persistent and statistically significant for all time-points in the series.
For 2022, the proportion of respondents rating their quality of life as good or extremely good was 60.8 percent for those aged under 65 years with a long-term health condition or disability, 56.8 percent for those aged 65 years and over with a long-term health condition or disability, and 88.1 percent for those without.
