Looking for data on Eastern European scientists working in Western Europe

Question

I would like to have statistics on Eastern European scientists working in Western Europe.

I have found some related papers like Brain Drain in the European Union: Facts & Figures or Emigration from Eastern Europe with a Focus on Brain Drain but these do not contain data material for knowing how many scientists move from Eastern Europe to Western Europe.

Could you help me finding a reliable data source on this?

Answer 1

The German Federal Statistics Office was so kind to provide me data on the issue in Germany:

https://www.destatis.de/DE/Publikationen/Thematisch/BildungForschungKultur/Hochschulen/PersonalHochschulen.html

On page 190, you will find the table

13 Wissenschaftliches und künstlerisches Personal nach Herkunftsländern und Fächergruppen der fachlichen Zugehörigkeit

that is, scientific and art personnel according to their original country and per job area.
