South Korea\'s jobless rate for 2012 could rise to 5.8 percent if \"underemployed\" people and other at-risk populations were counted, a report showed Friday, showing a large gap with the government\'s official figures. According to the report compiled by the Woori Finance Research Institute, the country\'s effective jobless rate could rise sharply if counting such people deemed to face almost the same tough working conditions as those technically remaining out of work.
