Frequently asked questions

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

6,236 scientists affiliated with India are on the 2025 single-year list, and 3,371 are on the career-long list.

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

On the 2025 career-long list, Indian Institute of Science has the most listed scientists from India, with 134. It is followed by Indian Institute of Technology Delhi with 105.

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

On the career-long list, India went from 1,491 scientists in 2020 to 3,371 in 2025, a change of +126.1%.

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.
