About these figures

A snapshot of how OpenAlex classifies the published output of researchers by institution and broad subject. Sources: OpenAlex, HAL and DOAJ.

Counts are records, not verified people — roughly 6.7 % share a name with another record, so totals are an upper bound.
Subjects are classifications of published work, not skills anyone declared. Locations are the institution’s, not the person’s.
There is no time dimension: nothing here describes trends, growth or how recent a researcher’s work is.
Coverage reflects what OpenAlex indexes and what we collected — not a country’s research capacity.
