Frequently asked questions

How many scientists from Slovenia are in the 2025 Stanford Top 2% list?

204 scientists affiliated with Slovenia are on the 2025 single-year list, and 217 are on the career-long list.

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

On the 2025 career-long list, Univerza v Ljubljani has the most listed scientists from Slovenia, with 75. It is followed by Institut Jožef Stefan with 50.

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

On the career-long list, Slovenia went from 114 scientists in 2020 to 217 in 2025, a change of +90.4%.

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.
