Singapore workers median gross monthly income increased more than 20% over past 5 years

According to information provided in the Report on Labour Force in Singapore 2008 published by Singapore's Ministry of Manpower, the median gross monthly income of Singapore employees (especially the full time employed workers) has increased by more than 20% over the past 5 years.

The median income by June 2008 stood at S$2,450.

"Income typically rises with educational attainment, reflecting the premium that employers place on education and skills. In June 2008, full-time employed residents with degrees commanded a median income of $5,060, 4.2 times the $1,190 for those with primary or lower qualifications."

I wonder if the Ministry of Human Resource in Malaysia conducts similar survey, and how will the figure be like?
