Frequently asked questions

How many scientists from Greece are in the 2024 Stanford Top 2% list?

1,019 scientists affiliated with Greece are on the 2024 single-year list, and 1,065 are on the career-long list.

Which institute in Greece has the most Top 2% scientists?

On the 2024 career-long list, Aristotle University of Thessaloniki has the most listed scientists from Greece, with 157. It is followed by National Technical University of Athens (NTUA) with 136.

What is the difference between the single-year and career-long lists?

The single-year list ranks scientists on the citations their work received in one year. The career-long list ranks them on citations across their whole career. Both lists are published every year, and a scientist can be on one, both or neither.

What is the official source of this data?

The rankings come from the science-wide author databases of standardized citation indicators published by Ioannidis et al. in the Elsevier Data Repository, updated every year. TOPSCINET, an independent platform, organises that data by country, year, institute and field, so you can compare and explore it.
