A city carries no overall standing here. The composite score is built for institutions and countries, the units its floors and field normalisation were designed around. An empty rank on this page is a statement about the measure, not about the place.
Which research institutions are in Leiden?
By fractional works over the whole record; world rank on research quality in 2022–2025. Bars are scaled to the largest institution in this city, not to anything off the page.
How concentrated the city is
The same institutions as shares of everything the list accounts for. A city that is one university and a city that is twelve read alike as a table and not at all alike here.
