Recently, Hong Kong has been ranked in the list of Healthiest, Happiest and Most Expensive countries/cities to live in respectively:
Bloomberg Global Health Index - (outside of Top 50)!
Bloomberg Global Health Index - (outside of Top 50)!
World's Happiness Report 2017 - ranked #71
Economist Intelligence Unit, Most Expensive- ranked #2
On the same note, the city of Singapore is ranked #25 (but #1 in Asia) and #1 as the world's happiest and most expensive city respectively. Happy and expensive in correlation? Would be strange to think so.
