Frequently asked questions

How many scientists from Ireland are in the 2020 Stanford Top 2% list?

586 scientists affiliated with Ireland are on the 2020 single-year list, and 547 are on the career-long list.

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

On the 2020 career-long list, Trinity College Dublin has the most listed scientists from Ireland, with 108. It is followed by University College Dublin with 99.

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.
