Vienna, Austria, may be most widely known for its famous Opera House, historic museums and coffee shop culture dating back over a hundred years. But now it's also the most liveable city in the world. The European city was ranked No. 1 in the world in The Global Liveability Index 2018, an annual report by The Economist Intelligence Unit released August 14. It's the first time the city ranked as the most livable out of 140 cities surveyed, displacing Melbourne, Australia from the top spot, which had a record seven-year winning streak.

For its methodology, The EIU assessed which locations around the world provide the best or the worst living conditions. Every city is assigned a rating of relative comfort for over 30 qualitative and quantitative factors across five broad categories: stability (looking at things like crime, conflict and terrorism), healthcare, culture and environment, education, and infrastructure.
