About 64 percent of the people who graduated from college this spring have found employment, the second straight year the figure has improved, according to preliminary government data.

Despite the improvement, an education ministry official cautioned that "the situation remains severe" as employment conditions are becoming more unstable for young people.

The preliminary data, released Monday by the education ministry, showed that the employment rate stood at 63.9 percent, up 2.3 percentage points from last year. Meanwhile, 128,224 graduates, or 22.9 percent of the total, have neither found work nor advanced to graduate studies.

According to the data, 559,030 people graduated from college in March, of which 357,285 have secured jobs, including nearly 22,000 who were hired on a temporary basis.

The employment rate for high school graduates was 16.8 percent, compared with 16.3 percent last year, also marking the second straight year of growth.
