The government said Tuesday more than 80 percent of young people are worried about their incomes and postretirement pensions amid the downbeat job market and low salaries.

The figure obtained through an online survey conducted between December and January was included in the 2012 white paper on children and youth approved by the Cabinet on Tuesday.

The survey of people 15 to 29 received 3,000 valid responses.

In response to a questionnaire on various worries concerning employment, 82.9 percent said they are "worried" or "rather worried" about whether they will be able to earn enough in the future and 81.5 percent expressed concern about receiving a pension following retirement, according to the white paper.

Asked about the purpose of working, 63.4 percent replied to "earn wages," followed by 51 percent who said that they work "for a living," the paper said. The respondents were allowed to choose multiple answers.

A separate white paper on children and child-rearing, also approved Tuesday, said 86 percent of surveyed married women raising children would like to work either as regular employees or as part-timers, reflecting the desire for dual-income households amid the protracted economic downturn.

The online survey conducted in November covered married women aged between 20 and 49 with children under 19.
