From the Economist Intelligence Unit:
The latest findings of The Economist Intelligence Unit’s Global Liveability Ranking – which provides scores for lifestyle challenges in 140 cities worldwide – show that although Melbourne has retained its crown as the world’s most liveable city, liveability has deteriorated in 29 of the 140 cities (20 per cent) surveyed over the last 12 months.
The decline is largely a result of heightened fears over terrorism with more than 1,000 reported attacks in 2016 so far, with incidents in France, Turkey, the US and Belgium being the most high profile. Factors such as social unrest in many US cities due to the deaths of black people in police custody, tensions in Eastern Europe and Asia and the ongoing civil wars in Ukraine, Syria and Libya have compounded the decline.
