A worldwide geographic map of the popularity of K-pop unveiled by fandom lab Blip offers some surprises. The city that loves K-pop the most is not its home of Seoul but Ho Chi Minh City, and densely populated Indonesia has as many people who listen to K-pop as Korea.

Bangtan Boys, also known as BTS, perhaps less surprisingly, are the most beloved K-pop combo, but Black Pink, EXO, Momoland and TWICE also have such strong fan bases as well.

Blip analyzed YouTube data on 76 K-pop idol bands from July 2018 to July 2019. Over 26.55 billion searches have been made on YouTube worldwide, and only 10.1 percent came from Korea, meaning the rest were watched abroad.

This is the first time the global popularity of K-pop has been quantified.
