Data confidence level:
This FACT indicates the results of a qualitative survey, AUSPOLL survey', measuring how liveable residents considered their city to be. Although 'liveability' as a concept is subjective, qualitative data is sought after in both the public and private spheres, it used by public and private bodies to make informed policy and investment decisions. While there is no definitive set of criteria that constitute liveability, there are some commonly acknowledged characteristics of cities that enhance quality of life. In 2013, the annual survey of Australian cities was commissioned by the Property Council of Australia (PCA). It asked people to rank the importance they placed on a set of 17 attributes that make their city liveable, grouped as follows: safety, accessibility, affordability, health, diversity, environmental sustainability, quality design and amenity. For the first time in four years, Canberra trumped Adelaide in the report for the nation's most liveable city.
