I am looking for statistics of research done in mathematics and computer science by country. I found reports for Thainland, Kyrgyzstan and Finland in mathematics. Where can I find similar statistics for other countries, and also the "bigger" ones like USA, Russia, UK, France, Germany etc.
Things that should be mentioned are: Major universities/institutes, what was achieved in the last decades, research output, people, topics and conferences held and a general overview. So how to find such information?
