The index ranks 140 cities on stability, healthcare, education, infrastructure, culture and environment, giving each city a rating out of 100. Last year, Vienna (97.4) and Melbourne (97.5) were incredibly close, but this year the Austrian capital has pipped the reigning champions.
While none of Melbourne's ratings dropped — its overall ranking actually climbed to 98.4 — Vienna's stability and culture and environment ratings increased, which The Guardianis attributing to downgraded threat's of militant attacks in western Europe and the city's low crime rate.
The Economist said, "Although both Melbourne and Vienna have registered improvements in liveability over the last six months, increases in Vienna's ratings, particularly in the stability category, have been enough for the city to overtake Melbourne.
While Melbourne dropped, Sydney managed to climb the ranks (huzzah) — coming in at fifth this year, compared to last year's eleventh. Rounding out the top five were Osaka at third and Calgary at fourth.
