Among the top 10 cities were Melbourne, Sydney and Adelaide from Australia, Calgary, Vancouver and Toronto from Canada and Osaka and Tokyo from Japan. Copenhagen ranked ninth was the only other European city in the top 10. The German city of Hamburg, which had remained in the top 10 since 2015, was pushed to 18th position despite its score remaining at 95.0. Auckland was pushed from eighth to 12th position, Perth from seventh to 14th and Helsinki from ninth to 16th.
