the list goes on like this. when all the squads are reviewed, some interesting notes emerge.
it turns out there's no national team whose entire 26-man squad plays in its own domestic leagues. the national teams closest to this are qatar and saudi arabia, with 25 players each. as the exact opposite of the above situation, none of the players in the curaçao, cape verde, democratic republic of congo, uruguay, ivory coast, and senegal national teams play in their own countries' leagues. in fact, apart from uruguay (1 player), not a single player from the other countries' leagues is in any other country's national team either.
participant countries' populations as a share of world population: participant countries with the highest populations: usa 340 million, brazil 315 million, and mexico 130 million.
participant countries with the lowest populations are curaçao at 195 thousand and cape verde at 570 thousand.
the total population of the participant countries is roughly 2,200,000,000. if we divide it by the current world population (8,300,000,000), this ratio comes out to 26.5%. for the 2022 qatar world cup: 1,600,000,000 / 8,000,000,000 = 20%
for the 2018 russia world cup: 1,650,000,000 / 7,700,000,000 = 21.4% as can be seen, even though the number of teams in the tournament was increased by 50%, the rate of increase in the participant countries' populations stayed at around 25%.
confederations' representation rates:
the number of players playing at clubs registered with uefa is 855 (68%). the number of countries participating from uefa is 16. the quota ratio is 16/48 = 33%.
following this federation most closely is the afc (asia) (15%). this confederation's quota is 9. the quota ratio is 9/48 = 18%.
caf (africa), meanwhile, got a 21% country quota with a 4 percent player quota. fine, let's say that's tolerable. after all, some of the countries participating from uefa have players of african origin.
representation of players of african origin in the national teams of uefa member countries: france – 21 england – 15 netherlands – 14 switzerland – 11 belgium – 9 germany – 9 sweden – 6 portugal – 4 austria – 4 norway – 2 spain – 2 scotland – 1 czechia – 1 croatia – 0 bosnia and herzegovina – 0 turkey – 0
