Frequently asked questions

How many scientists from Poland are in the 2021 Stanford Top 2% list?

1,027 scientists affiliated with Poland are on the 2021 single-year list, and 957 are on the career-long list.

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

On the 2021 career-long list, AGH University of Science and Technology has the most listed scientists from Poland, with 50. It is followed by Politechnika Warszawska with 49.

How has the number of Top 2% scientists in Poland changed since 2020?

On the career-long list, Poland went from 726 scientists in 2020 to 957 in 2021, a change of +31.8%.

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.
