24. Singapore
This island nation has probably the highest standards of living in Asia. Hence people are attracted to business opportunities the place has to offer and the huge numbers of shopping malls that attract buyers in droves from all corners of the earth. This once British colony is known for immaculate cleanliness and orderliness. Last but not the least, tourists come in to soak in the fabulous skyline as seen at night from the waters of the Singapore Strait. As many as 17.4 million tourists converged in 2017 on this tiny 270 sq km island-nation ranked 176th in size.
