TAIPEI, May 8 (Xinhua) -- Over 20 percent of working women in Taiwan rated their own stress levels as over 80 on a 100-point scale, a survey showed Tuesday.

Nearly 60 percent of 1,158 respondents rated their stress as above 60 points, according to a survey by local job-seeking platform 1111 Job Bank.

It found that the most significant sources of stress for single women were a lack of savings, low salaries and unbearably high housing prices, while "being single" still troubled some 41 percent.

For married women, stress mainly came from being unable to find a more suitable job and long commuting distances.

The minimum average monthly income for a family to afford a child was 74,965 new Taiwan dollars (about 2,517 U.S. dollars), the survey report said.

Meanwhile, the workplace and family pressure clearly affected the confidence of working mothers.

Based on their self-evaluations, working mothers rated their average performance at work as 73.6 and as mothers at 52.3 points out of 100, according to a separate survey conducted by competing website yes123.
