Method
Subjects follow the OpenAlex taxonomy, on the profiles that carry one; a person can carry several, so shares are shares of subject assignments. A country is where the institution sits. Newcomers are dated by first publication, and a doctorate in progress is a junior profile with a first publication and no dated defence. The index is built from arXiv, OpenAlex, ORCID and DBLP and grows every night. See the atlas, how to find and hire AI researchers and how long an AI doctorate takes.
