How to use these university counts
- Treat each affiliation string as the dataset wrote it (University of Oxford ≠ University of Oxford Medical Sciences Division; University College London ≠ UCL Queen Square Institute of Neurology; University of Cambridge ≠ Trinity College Cambridge).
- Switch single-year vs career on the institution page — career UK totals 21,340 scholars; single-year totals 18,269.
- Open a scholar profile, then the certificate page if you need a printable overlay.
- For journal-level context when you cite their papers, use the Journal Quality Report.
