Ranking of chess countries according to their young players
November 2011

Criterion: sum of world ranks in each category
Category U10 U12 U14 U16 U18 U20
Number of players 1* 2 2 2 2 1*
* I think U10 and U20 are not the best categories to determine the strength of a country, so I decided to count only the best player's rank, whereas in other categories it's best two's ranks.

You will find below chess countries ranked by the sum of world ranks of their best players.
The above table means it's based on 10 players : best U10, best two U12, best two U14, best two U16, best two U18 and best U20.
Pen. (for penalty) is the number of missing player (= no player in U10 or U20 or only one in other categories). I chose to rank only countries with 1 missing player out of 10, max.
