Korean Groups Look Shortest-Lived on Wikidata. The Cohorts Are 31 Years Apart
Among groups with a recorded end date on Wikidata, Korean groups' median lifespan is 3 years against 5-7 for Japan, the US and the UK. Not a ranking — the Korean cohort was founded a median 31 years later than the UK's.
The table this is written from: /what-moves-english-reading
We set out to compare how long Korean, Japanese, American and British music groups last before disbanding, using the dissolution year Wikidata records for each group. The number came out cleanly — and we are not publishing it as a ranking, because the dataset itself rules that out.
What the raw numbers show
| Country | Groups countable | Have a recorded end date | Median lifespan | Ended within 10 years | Median founding year (recorded-ended) |
|---|---|---|---|---|---|
| South Korea | 691 | 67 (9.7%) | 3 years | 97.0% | 2011 |
| Japan | 1,373 | 110 (8.0%) | 6 years | 70.9% | 1999 |
| United States | 10,844 | 223 (2.1%) | 7 years | 70.4% | 1990 |
| United Kingdom | 3,768 | 143 (3.8%) | 5 years | 69.9% | 1980 |
Read on its own, the Korean row looks like the shortest-lived group culture of the four. It is also the youngest one, by a lot.
Why we’re not calling this a ranking
The median founding year for groups with a recorded end date spans 31 years across the four countries — 2011 for the Korean cohort down to 1980 for the British one. A group that Wikidata says formed in 2011 has had, at most, 15 years to accumulate a recorded run; a group from 1980 has had 46. Comparing “how long did this group last” across cohorts that far apart in age is comparing groups that have not had equal time to prove out a long run, not comparing four countries’ actual group culture.
This is also why the share with any recorded end date at all varies so much — 9.7% for Korea against 2.1% for the US. That gap could reflect real differences in how actively each country’s fan and editor communities maintain group pages, how many groups have quietly stopped without anyone recording it, or something else the data does not show. We do not know which, so we do not guess.
What we can say
The one thing that holds regardless of cohort age: across all four countries, a large majority of the groups that do end are recorded as ending within 10 years of forming (69.9% to 97.0%). A group lasting past its first decade is the exception everywhere we measured, not the rule — even if we cannot say which country’s exception rate is genuinely lowest.

Where these numbers come from
Sources
- Wikidata — Music groups (and subtypes reached via P31/P279*) with a recorded country and, where present, a dissolution year. · https://www.wikidata.org/
What we checked
- South Korea: 691 groups countable, 67 (9.7%) have a recorded end date. Of those 67, median lifespan is 3 years and 97.0% ended within 10 years. Median founding year among the recorded-ended group: 2011.
- Japan: 1,373 countable, 110 (8.0%) recorded ended. Median lifespan 6 years, 70.9% within 10 years. Median founding year: 1999.
- United States: 10,844 countable, 223 (2.1%) recorded ended. Median lifespan 7 years, 70.4% within 10 years. Median founding year: 1990.
- United Kingdom: 3,768 countable, 143 (3.8%) recorded ended. Median lifespan 5 years, 69.9% within 10 years. Median founding year: 1980.
- The founding-year medians span 31 years (2011 down to 1980) across the four recorded-ended cohorts. A group founded more recently has had less time to accumulate a long recorded run — so a shorter recorded Korean lifespan is exactly what a younger cohort would produce even with no real difference in how long groups actually last.
What we left out, and why
- A ranking of which country's groups 'last longest.' We built the four-country table and are not publishing it as a ranking, for the cohort-age reason above.
- Groups without a recorded end date. For Korea, that is 90.3% of the countable list — most Korean groups' status is simply not recorded on Wikidata, not confirmed as still active or as disbanded quietly.
- Any single group's story. This measures Wikidata's record-keeping, not any act's actual history.
