South Korean households' income grew 2.1 percent on-year in 2013 thanks in part to improved labor market conditions that led to more employment, a government report showed Friday, although the slow pace of growth suggests a lingering economic slump. According to the report by Statistics Korea, the monthly income of households consisting of two members or more stood at an average of 4.16 million won (US$3,875) last year, up from 4.07 million won tallied a year earlier.
