Median monthly household income from work rose from $7,040 in 2011 to $7,570 last year, said the Department of Statistics Singapore on Wednesday.

This is a 7.5 per cent increase in nominal terms, or 2.7 per cent after factoring in inflation.

Taking into consideration changes in household size, median monthly household income from work for each household member rose by 1.9 per cent in real terms over the same period, and 13 per cent over five years from 2007 to last year.

The report from the Department of Statistics also noted that the Gini coefficient, a measure of income inequality, increased from 0.473 in 2011 to 0.478 last year.

But after taking into account government transfers and taxes, the figure is 0.459.
