International Mathematical Olympiad Cumulative Results by Country until now

  • Females participation is very low. None of Arab states is among the top 50. From The Middle East, only Iran appears in the top 20 countries (12th).

  • USSR and Russia are split for some reason there, cumulative number is noticeably higher.

    Same goes for other countries - Yugoslavia, Czechoslovakia, etc.

    What a mess honestly :D Same people, different brands.
