According to this article (http://theonlinecitizen.com/2010/11/over-30-earn-less-than-1200/) 30% of Singaporeans earn less than $1200 per month. With deductions for CPF the take-home salary for these people will be less than $960 (not included are deductions for CDAC, MENDAKI or SINDA). Which means that even if two persons in such households of four members are employed, they merely live from hand to mouth.
According to Key Household Income Trends, 2009, those living in 1 and 2 room flats had a median income of only $1091. I wonder how these families survive month to month?
