Singapore - The 6th Costliest City In The World

This is expected,but quite a skewed measure in my opinion actually.It should be higher up the list.Using GDP per head isn't as accurate as using real residual income per head,I don't feel its any use measuring the individuals expenditure when the person has little left over.

For example take individual A earning S$5,000 and spending S$3,000 on transportation and housing.That person will have S$2,00 left over.Another individual B living in another city earns the equivalent of S$5,000 as well,but spends S$1,000 on both housing and transportation.Assume homes and cars are of equal quality class.Although individual B will have a higher GDP per head, he/she has less residual income.Residual income and purchasing power are the best gauges,not GDP in my opinion.
