The most Korean superrich in terms of stock value were found to live in Yongsan-gu in central Seoul, data showed Sunday.

According to corporate information provider Chaebul.com, 19 percent, or 48 of 243, of rich individuals owning over 100 billion won ($88 million) in stocks live in Hannam-dong and Itaewon -- both of which are in Yongsan-gu, Seoul. Among them, 14 were found to possess over 1 trillion won in stocks.

The Itaewon residents include AmorePacific Chairman Suh Kyung-bae as well as those from the Samsung family -- Chairman Lee Kun-hee, Samsung Electronics Vice Chairman Lee Jae-yong and Samsung C&T fashion business chief Lee Seo-hyun.

Those living in Hannam-dong include Hyundai Motor Group Chairman Chung Mong-koo, SK Group Chairman Chey Tae-won, LG Group Chairman Koo Bon-moo, Shinsegae Group Chairwoman Lee Myung-hee and SDJ Corp. Chairman Shin Dong-joo.

The total stocks the 243 superrich own amounts to 122.5 trillion won, for an average of 504 billion won.

The average stock assets of superrich living in Hannam-dong and Itaewon was 1.28 trillion won per person, the highest in the country.

Those in Seongbuk-dong in Seongbuk-gu, northern Seoul, ranked second with 314 billion won per person, followed by those in Bundang in Gyeonggi Province, at 343 billion won.

Seongbuk-dong is home to 24 of the stock rich, including BGF Retail Chairman Hong Suk-jo, Hyosung President Cho Hyun-joon and Hyundai Group Chairwoman Hyun Jeong-eun.

Meanwhile, the Gangnam region of southern Seoul -- Gangnam-gu, Seocho-gu and Songpa-gu -- houses 38 percent of the stock rich, with many being among the second generation of chaebol owners or those who became rich through venture businesses. The latter includes NHN Chairman Lee Hae-jin, NHN Entertainment Chairman Lee Joon-ho, Kakao Corp. Chairman Kim Beom-su and NCSoft Chairman Kim Taek-jin.

Those among the second generation of chaebol families include Suh Min-jung, the eldest daughter of the aforementioned AmorePacific chairman.

Superrich wishing to reside out of Seoul mostly prefer Bundang in Seongnam, Gyeonggi Province, and Haeundae in Busan.

Shinsegae Group Vice Chairman Chung Yong-jin and LS Group Chairman Koo Ja-yeol reside in Bundang, while Nexen Tire Chairman Kang Byung-joong and Cuckoo Electronics Chairman Koo Ja-shin live in Haeundae.
