Koreans in Indonesia numbered 78,676 individuals , making them the 13th-largest population of overseas Koreans, according to South Korea's Ministry of Foreign Affairs. The number has increased significantly from previous record, which was around 50,000 people. Migration history One of the leading figures of the Indonesian independence movement, Komarudin (Korean name: Yang Chil-seong; Hangul: ; Hanja: ) was an ethnic Korean. The Korean presence in Indonesia goes back several decades. The Jakarta International Korean School in East Jakarta opened on 1 February 1975, and as of 2007 enrolled 719 elementary school students, 357 middle school students, and 375 high school students. It is thus the largest Korean day school in Southeast Asia, at more than twice the enrollment of the one in Ho Chi Minh City. A Koreatown began to form in South Jakarta's Kebayoran Baru subdistrict as early as 1982, when Kim Woo-jae opened a shop selling kimchi and doenjang. Between 2011 and 2013, their population increased by 11%. Nearly all (38,401, or 95%) are staying in Indonesia on ordinary residence visas. Other categories have shown rapid growth in recent years but remain small in absolute numbers: those on international student visas number 664 people (up 137% since 2011), 814 (up 285%) have permanent residence status, and 405 (up 58%) have become Indonesian citizens. The sex ratio of the community is unbalanced, with 1.3 men for every woman, similar to the pattern seen in most South Korean migrant communities in Southeast Asian countries besides Malaysia and Singapore; however, the imbalance has decreased from earlier years. Unlike Japanese expatriates of earlier years, most South Korean expatriates come accompanied by their families. Business and employment Most South Korean migrant workers in Indonesia are employees of South Korea multinational conglomerates with investments in Indonesia, or owners of small and medium-sized enterprises. Labour relations at South Korean-owned factories were poor in the 1990s, but have improved in recent years. Distribution In 2005 there were about 30,000 South Koreans living in Indonesia, with most of them being in the Jakarta area. Of the rest, 1,200 lived in Surabaya, 600 lived in Bandung, 150 lived in Bali, and 550 lived elsewhere. The main Korean areas in Jakarta proper are Cibubur in East Jakarta and Kelapa Gading and Sunter in North Jakarta. There are also Korean populations in Bogor, Cikarang in Bekasi Regency, and Tangerang. Most of the Bekasi Koreans work for the electronics industry. In
