South Korea's real household income increased and income distribution improved for the first time in some two years, providing a momentum for the Moon Jae-in government's so-called "income-led growth" policy.

According to Statistics Korea on Thursday, the average monthly nominal income earned by households with two or more members stood at four-point-44 million won in the fourth quarter last year, up three-point-one percent year-on-year.

Nominal household income growth surpassed three percent for the first time in about two years. 

The rise in nominal income led to an increase of one-point-six percent in the real household income over the same period. 

Real household income posted growth for the first time since the fourth quarter in 2015.

Indicators of income distribution also improved for the first time in eight quarters.

The disposable income of the top 20 percent income bracket was four-point-61 times higher than that of the bottom 20 percent during the fourth quarter last year, down from four-point-63 times from a year earlier, indicating a decrease in disposable income disparity.
