Which star signs actually end up in the same K-pop group

If you came looking for zodiac compatibility, this is what we can honestly show you: not whether two signs get along, but how often they have actually stood on the same stage.

We do not read star signs. Every number here is a count of recorded birth dates. There is no claim anywhere on this page that one pairing is better than another.

The answer first

Across 259 K-pop groups and 1,513 members whose birth date is on record, there are 4,651 pairings of one member with another. The most common pairing of signs is Leo + Aquarius, 93 times. Chance alone would give 82.1.

That is the whole story. Of the 78 possible pairs, the one furthest above chance is Leo + Scorpio at 1.25×, and the one furthest below is Virgo + Libra at 0.75×. With counts this size, gaps that size are what randomness produces. No two signs find each other, and no two avoid each other.

What was counted

Every pair, most common first

Why a pair is common has nothing to do with the pair

Leo + Aquarius tops the table because those are two of the commonest signs among K-pop members, not because anything draws them together. That is exactly why the by chance column is here. A raw count on its own invites a reader to find meaning in it; the two columns side by side take that back.

The one place our data does bend is the calendar, not the pairing — K-pop birthdays are not spread evenly through the year, and July is the thinnest month. We measured that separately, and it is a fact about when people are born in Korea rather than about star signs.

How many members each sign has

This is the denominator behind every by chance figure above. The spread is real but modest — the commonest sign has 67% more members than the rarest, across 1,516 members in total.

What we could not measure

• Whether two signs get along. We do not read star signs and make no claim about compatibility. This is a count of who was in a band with whom
• Why a pair is common. Agencies do not pick members by birthday; a pair is common mostly because those signs are common
• Members whose birth date is not on record. They are left out of the count rather than filled in

Two things that would bend these numbers

• A person in two groups is counted in both. That is what "times they were in a band together" means
• The expected column assumes each seat in a group is filled independently, which is an approximation, not a model of how groups are formed

One more, and it cuts against us: a member sits in many pairings at once, so the pairs are not independent of one another. Any test that treats them as independent will overstate how surprising a gap is. We mention it because it makes our own “nothing sorts” conclusion stronger, and a limitation that only ever helps the writer is worth suspecting.
