One Seoul arts high school crosses more languages than SKY combined

Korean pop culture is exported. The people who carry it are educated in Korea, and Korea keeps a public record of where. Wikidata holds a school for 4,535 Korean entertainers. Nobody had counted what those schools have in common.

We joined that table to a second one holding each person’s birth year and their sitelink count — the number of Wikipedia language editions that carry an article about them. Every one of the 4,535 matched. The measure is narrow and worth stating plainly: a sitelink count says how many language communities wrote about a person. It does not say how many people watched them.

The top of the table is a high school

Twenty-three schools have 40 or more recorded alumni. All 23 are below, in full, ordered by the share reaching ten or more language editions. The school at the top is not a university.

The three bolded rows are SKY — Seoul National, Korea and Yonsei, the universities Korean parents name when they name the top. Between them they have 197 recorded entertainers and 53 who reached ten languages. School of Performing Arts Seoul has 125 and 73.

The median is the sharper number

The share above uses a threshold, and thresholds can be argued with. The median is harder to argue with, because it describes the ordinary graduate rather than the successful one.

At School of Performing Arts Seoul the median alumnus sits in 13 language editions. At Yonsei the median sits in 2. At Ewha it sits in 1 — meaning the typical recorded entertainer from Ewha has a Korean Wikipedia page and nothing else.

Two people explain the arts-school figure better than any rate does. Jungkook of BTS and Jisoo of BLACKPINK both attended School of Performing Arts Seoul, and both appear in 68 language editions — the joint highest in the school’s list. Kang Seul-gi of Red Velvet is at 59, Bae Suzy at 51.

Hanlim Multi Art School, second among the arts schools, reads the same way: Kim Da-hyun of TWICE at 41, Cha Eun-woo at 39, Krystal Jung at 36, Son Chaeyoung of TWICE at 35, Lee Taemin of SHINee at 34.

What the elite universities produce instead

Yonsei’s list is not empty of names. It is led by J.Y. Park, the producer who founded JYP Entertainment, at 28 language editions, then the actor Park Gyu-young at 23. Seoul National’s is led by the actor Kim Tae-hee at 39 and Lee Soo-man, who founded SM Entertainment, at 30. Korea University’s by Ok Taec-yeon of 2PM at 29 and the actor Jeon Do-yeon at 25.

The pattern in those three lists is actors, producers and founders — people whose work reaches audiences through Korean-language institutions. The arts high schools produce idols, and idol groups are marketed to language communities one at a time.

The largest school is not the strongest

Seoul Institute of the Arts records 352 entertainers, more than any other school in the data, and 109 of them reached ten languages. That is the largest absolute count in the table and a 31.0% share — below Seoul National University’s. Chung-Ang University is similar: 310 recorded, 34.8%.

Volume and reach are separate axes here, and a ranking by one is not a ranking by the other. Anyone comparing schools should say which they mean.

Where this stops

Arts high schools audition applicants. Agencies recruit at them. A student is often already signed before the first class. So none of these figures separate what a school taught from whom it admitted, and this count cannot tell those apart — nothing here says a school caused anything.

The 4,535 people are those Wikidata records a school for. Our birth table holds 9,249. The other 4,714 are not people without schools; they are people whose schools nobody wrote down.

This is a count of public records, not a ranking of schools.
