By fractional works over the whole record; world rank on research quality in 2022-now. 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.
Shares of the rows listed above, not of the whole node.
Which fields of science does Leiden work in?
In 2022-now, 30% of research in Leiden is in Health Sciences, 30% in Social Sciences. Its largest fields are Medicine (27%), Social Sciences (16%), Biochemistry, Genetics and Molecular Biology (8%). It does 1.3× the world's share of Life Sciences.
Each ring splits the one inside it: the four domains of science, their fields, their subfields. Size is fractional works in 2022-now. Every slice is a page; the interactive view zooms down to single topics and colours each by how much more of it this city does than the world.

Location quotient against the world baseline. Inside a single field a city is a meaningful unit, which is why this is where a city is measured at all.
The whole field profile
All 26 fields at once: above the ring is more than a place this size would be expected to do. A specialist and a generalist produce the same ranked list and a completely different shape.
Rings at 0.5×, 1× and 2×. Widest outward: Immunology and Microbiology, 2.3×. Every wedge is a field page.
