The number of families where both the husband and wife work increased in 2014 amid the protracted economic slump, a report showed Tuesday.
  

According to the report from Statistics Korea, some 5.18 million households had dual incomes, accounting for 43.9 percent of all South Korean married couple households, which is also up 2.6 percent from 5.05 million tallied the year before.
  

The latest numbers showed that there was a noticeable increase in dual income earners for households headed by people in their 50s and 60s.
  

Dual income for households run by those in their 60s and older rose 6.7 percent on-year, with the numbers climbing by 4.7 percent for married households headed by those in their 50s.
  

Numbers also edged up 0.2 percent for households with the principle bread-earner in their 40s, but declined for younger families, mainly because of a population decrease.
  

The report also showed that 16.3 percent of all wage earners took advantage of the flexible working hour system. The total number of people who used the system reached over 3.09 million as of October 2014, up more than 125,000 from the year before.
  

Of workers who have never used the flexible working system, 34.2 percent said they wanted to utilize it in the future.
