FIFA
In total, FIFA recognises 211 national associations and their associated men's national teams as well as 129 women's national teams; see the list of national football teams and their respective country codes. FIFA has more member states than the UN as FIFA recognises 23 non-sovereign entities as distinct nations, such as the four Home Nations within the United Kingdom and politically disputed territories such as Palestine.
FIFA World Cup
The tournament was expanded to 24 teams in 1982, and then to 32 in 1998, also allowing more teams from Africa, Asia and North America to take part. Since then, teams from these regions have enjoyed more success, with several having reached the quarter-finals: Mexico, quarter-finalists in 1986; Cameroon, quarter-finalists in 1990; South Korea, finishing in fourth place in 2002; Senegal, along with USA, both quarter-finalists in 2002; Ghana, quarter-finalists in 2010; and Costa Rica, quarter-finalists in 2014. Nevertheless, European and South American teams continue to dominate, e.g., the quarter-finalists in 1994, 1998, 2006 and 2018 were all from Europe or South America and so were the finalists of all tournaments so far.
