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.
