Singapore 新加坡
With one of the highest population densities in the world and denizens known for being workaholics, it's hard to imagine the city-state of Singapore having one of the happiest populations on earth. And yet in a recent survey, 95% of them said they were either very happy or quite happy. They give their city high marks for cleanliness and safety—subways are pristine and unfailingly arrive on time, and police are seen as helpful and good at their jobs. What's more, they feel they can count on their neighbors—all 5.1 million of them. As Ahmad Nizan Abbas, a lawyer from Singapore, explained, "We used to live in fishing villages where we pulled together to help each other... If something happens to a Malay household, the whole Malay community will be there to lend support."
