Australia and Canada were seen as having the most top ranked cities, with Melbourne coming first and Vancouver, Toronto and Calgary all making the top 10.
Of these changes, the majority have been negative, reflecting deteriorating stability, as cities around the world face heightened threats of terrorism or unrest.
The global liveability survey gave cities a rating which represents the challenges they present to lifestyle of people living there.
However, it has one of the most improved liveability scores over the last five years.
The cities are rated on the basis of stability (25%), health care (20%), culture and environment (25%), education (10%) and Infrastructure (20%). Neither city saw an improvement in their scores and their advances were largely due to declines in livability in other cities.
It's official ─ Manchester is the best city to live in the UK.
Of the top ten cities, three are in Australia, three in Canada and three in Europe. They offer a range of recreational activities, low crime levels and smart, stable infrastructure. "It's just more proof there's no city on earth quite like Melbourne", said Premier and all-round legend Daniel Andrews. Hit hard by terrorism are cities in France, Turkey, the United States and Belgium. It scored 38.7 out of the ideal score of 100, unchanged from last year's. Dublin beat both cities with a score of 89.5 and was ranked at number 40 globally.
"Terrorism has also been compounded by unrest and, in more extreme cases, civil war in some countries".
There are only 3.3 points between Melbourne and Brisbane, Australia's lowest-ranked city, in 16th place.
But "violent acts of terrorism" have affected many countries and while not a new phenomenon, the "frequency and spread have increased noticeably and become even more prominent in the past year", said the Global Liveability Report.
The cities that fared badly in the survey and came at the bottom of the list are Syria's capital Damascus, followed by Libya's Tripoli, Nigeria's Lagos, Bangladesh's capital Dhaka and Port Moresby of Papua New Guinea.
