Frequently asked questions

How many scientists from Norway are in the 2023 Stanford Top 2% list?

1,188 scientists affiliated with Norway are on the 2023 single-year list, and 1,315 are on the career-long list.

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

On the 2023 career-long list, Universitetet i Oslo has the most listed scientists from Norway, with 255. It is followed by Norges Teknisk-Naturvitenskapelige Universitet with 239.

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

On the career-long list, Norway went from 947 scientists in 2020 to 1,315 in 2023, a change of +38.9%.

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.
