Frequently asked questions

How many scientists from the Czech Republic are in the 2026 Stanford Top 2% list?

572 scientists affiliated with the Czech Republic are on the 2026 single-year list, and 622 are on the career-long list.

Which institute in the Czech Republic has the most Top 2% scientists?

On the 2026 career-long list, Charles University has the most listed scientists from the Czech Republic, with 83. It is followed by Academy of Sciences of the Czech Republic with 34.

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

On the career-long list, the Czech Republic went from 335 scientists in 2020 to 622 in 2026, a change of +85.7%.

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.
