Korean pop culture, in numbers

Which work is this chart row — reading a title against the markets it charted in

Two works can share a title. Which one charted?

Undercover took 48 chart places across 24 countries in our Korean panel. 33.3% of them were in Netherlands, and none were in South Korea.

Chart places. One place is one title in one country in one week.

Together they held 84 of 37,750 chart places — 0.22% of the panel.

The obvious test does not work

342 of 902 Korean titles (37.9%) never charted in Korea at all, because a drama that airs on Korean television does not appear on Netflix Korea. Absence from the home chart proves nothing on its own.

So a title is removed only when all three hold: it never charted in Korea, Wikidata attributes no Korean work at all to that name, and the market it charted in most is one Wikidata names as the origin of a same-titled foreign work. The middle condition is what makes it safe — a name a Korean work also carries is never removed.

Two we could not settle

TitlePlacesMarketWhy it stayed
Keys to the Heart3PhilippinesA Korean work carries this name
Life Is Beautiful2ItalyA Korean work carries this name

It cannot separate two works when a Korean work genuinely shares the name and the foreign one dominates the same market. Two titles failed here and were kept.

How this was counted, and what it cannot say

It says which work the chart row belongs to, not whether the other work exists, and it needs a foreign work Wikidata already knows about.
