The median income for all employed residents dipped by 1.2 per cent from $2,450 in 2008 to $2,420 in 2009.

Although median monthly income for full-timers rose slightly by half a percentage point (from $2,590 to $2,600), income as a whole fell as part-timers' share of employment rose. 

Part-timers also posted higher median income of $620 compared with $600 a year ago.

In contrast, incomes gained 11 per cent in 2008 and 7.7 per cent in 2007.

The global recession and its impact on Singapore led to a decline in the proportion of residents employed in Singapore, but older residents maintained their employment rate at the record high reached in 2008.
