South Korea will conduct a nationwide survey on the employment of foreigners living here to better understand their job conditions and set related policies, the statistical office said Monday.

Statistics Korea said 10,811 foreigners will be interviewed this year, up from around 10,000 in the past four years, during the survey that will start Tuesday and run through June 2, with some 1,000 people in Siheung, a city southwest of Seoul, to be checked in detail.

Roughly 8.9 percent of the city's population is made up of foreigners, making it the fourth-highest in the country after Yeongdeungpo and Guro wards in the capital city, and Ansan, an industrial city south of Incheon.

"One-on-one interviews will be carried out, although phone calls and self inputting of information will be carried out for people who are unable to meet pollsters," an official said. "The poll takes into account where they work and nationalities to get a comprehensive picture."

Data collected will be made public in October and November and be used to better grasp where foreigners are employed, the office said, adding the data will help make it easier to establish economic and immigration policies. (Yonhap)
