Illinois Department of Natural Resources

The fields where it stands highest, 2022–2025, ranked among every institution above the floor in each field.

Each strip is that field’s whole ranked pool, with the notch where Illinois Department of Natural Resources sits in it, in the colour of the band that rank falls in. The track under the rate is the rate itself: it carries no world mark, because the world rate differs by field (from about 6% to 21% in this record).

Where its research is concentrated relative to its size: Ecology takes 26.6× the share of its output that it takes of world research.

Location quotient, a volume reading rather than an impact one. It surfaces small, lopsided specialities.

Location quotient across every field it publishes in: outside the ring is more than an institution of this size would be expected to publish, inside it is less.
