Singapore is ranked as the 37th most liveable city in the world as Hong Kong overtook the Republic in the 2018 Global Liveability Survey.
In 9th place, Denmark's capital Copenhagen was the only other European city to rank in the top-10, while two other Australian cities feature in top-ranked places: Sydney (5th) and Adelaide (10th).
The study rates cities in the world using a number of measures, including stability, healthcare, culture and environment, as well as education and infrastructure, to calculate an overall liveability rating. Vienna got a score of 99.1, and Melbourne sits at an absolutely paltry 98.4.
EIU attributes Austria's capital's rise to the top to increased security scores due to a return to relative stability across much of Europe after high-profile terrorist attacks in recent years. Osaka in Japan came in at three and the Canadian city of Calgary followed.More news: Clarify activists arrests — European Union to Saudis

"Osaka stands out especially, having climbed six positions, to third place, over the past six months, closing the gap with Melbourne", the EIU's annual ranking report summary says.
"Although the cities ranked among the most liveable in the world remain largely unchanged, there has been pronounced movement within the top tier of liveability", the report said. "In its own turn, Singapore's score also registered an improvement in the public healthcare category, boasting the highest possible score", EIU said in its press release.
Alongside Paris, Manchester was the fastest-rising city in the Index, rising 16 places to 35, ahead of London in 48 place out of the 140 cities measured worldwide.
Hamburg and Helsinki, who held tenth and ninth place a year ago, have dropped out of the top ten. Wore-torn Syria saw its capital of Damascus rank last on the list as the country's bloody civil war continues to drag on. Almost half the cities in the survey saw their ratings improve over the past year.
