What is the best city in world for 2010?

As of my last update in September 2021, the best city in the world for 2010 was Vancouver, Canada.

However, please note that this information might be outdated as there have been new rankings and assessments done since then.

To obtain the most up-to-date information on the best city in the world, you can refer to recent reports or rankings from reputable sources such as The Economist Intelligence Unit's Global Liveability Index, Mercer's Quality of Living Survey, or Monocle's Quality of Life Survey.
