Hong Kong (CNN) — It's usually all about the top cities to live in when the Economist Intelligence Unit (EIU) publishes its annual livability ranking -- but this year the picture is rather more gloomy.
And that's because of a surge in global instability over the past 12 months, from terrorist shootings in France and Tunisia, to ongoing conflicts across the Middle East, Ukraine and Libya.
In any event, it's as you were for the "haves" at the top of list, with Melbourne taking the top spot for a fifth year running, with Vienna, Vancouver, Toronto and Adelaide/Calgary (tied at 5) completing the top five most livable cities in 2015.
According to the EIU, these cities have "relatively few challenges to living standards," and enjoy a good infrastructure, healthcare system and a low murder rate.

Unsurprisingly, Damascus remains the least livable city, with Syria embroiled in a bloody civil war.
"The EIU ranking, which provides scores for lifestyle challenges in 140 cities worldwide, shows that since 2010 average liveability across the world has fallen by 1%, led by a 2.2% fall in the score for stability and safety. While this may seem marginal, it highlights that 57 of the cities surveyed have seen declines in liveability over the last five years," this year's report stated.
Bucking the trend
By contrast, some regions have bucked the trend -- seven Chinese cities improved their ranking over the last 12 months "largely because of a lower threat from civil unrest," the report said. "Chinese cities saw liveability fall in the wake of riots and unrest in 2012, most notably due to widespread anti-Japanese sentiment."
China's top-ranked city, Beijing, moved up five places to 69 in the global ranking.

But Hong Kong's pro-democracy protests last year resulted in a 3.2% decline in livability. Though the protests were largely peaceful, some parts of the city were brought to a standstill for several months.
However "Asia's World City" still remained three places above city rival Singapore -- 46th and 49th place respectively.
"Hong Kong's liveability has been hit by the disruptive protests that took place last year. The city retains bragging rights over its regional competitor Singapore, but by a tiny margin. In fact both cities can still lay claim to being in the top tier of liveability where few, if any, aspects of life are restricted. This has not been the case in other parts of the world, with instability and unrest features undermining the scores of a number of cities globally," said Jon Copestake, editor of the EIU survey.
