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

On the 2020 career-long list, Alexandria University has the most listed scientists from Egypt, with 24. It is followed by Cairo University with 24.

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?
