How many world-class institutions does Hong Kong hold?

Average quality and elite capacity disagree by construction, and both are worth knowing: the first is decided by a country’s whole institution population, the second counts the institutions it holds at the top. One square per institution.

in the world top 50251st to 100th3501st to 1,000th2

Bands are exclusive, so the squares add up to 7 — the institutions it holds in the world top 1,000 — and not to four times it.
