Frequently asked questions

How many scientists from Portugal are in the 2022 Stanford Top 2% list?

770 scientists affiliated with Portugal are on the 2022 single-year list, and 515 are on the career-long list.

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

On the 2022 career-long list, Universidade do Porto has the most listed scientists from Portugal, with 77. It is followed by Instituto Superior Técnico with 73.

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

On the career-long list, Portugal went from 385 scientists in 2020 to 515 in 2022, a change of +33.8%.

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.
