Where is science strongest?
On research quality in 2022-now (excellence per paper, with output and breadth), United States, China and Germany rank highest overall. Every field has its own leaders: see a field's page for who leads it.

The track on each row is that row's top-10% rate. The tick is the average of all institutions, 10.0% (how it is set); teal is above it, red below. The ranking itself is the quality score, which compares the rate with what each place's own topics predict, adds its share of papers in the Nature Index journals, and counts output and breadth too.

Size against quality
The two things the ranking blends, on their own axes. The upper left is the interesting corner: places that publish less than the giants and land more of it in the world's top 10%.

What is a map of science?
A map of science shows where research happens and how fields relate. Science Explorer draws every research institution on a world map, sized and coloured by output, excellence or specialisation in whichever field you choose, and links each place, field and researcher to a page of its own. It follows a tradition of science mapping that runs from citation maps to Katy Börner's Atlas of Science, built here on open data.
