Football is a national sport in over 60 nations. to sum it regionally:
South America
Western Europe (all countries ranging form Norway down to Greece). Most people will argue that the majority of countries east of Germany (eastern Europe) regard Ice Hockey as their national sport over football, even though football still draws a huge following in those countries.
South East Asia (Countries ranging from Indonesia to the Thailand and Cambodia are not particularly strong in football, but it is watched and followed religiously in this part of the world).
Middle East (countries like the United Arab Emirates, Saudi Arabia, Iran, Iraq etc all play soccer as their national sport)
African Nations: Almost all African nations excluding South Africa have football as their national game.
Countries where soccer is NOT the national game but often mistaken to be; Mexico (apparently baseball is top) Japan (baseball) Cuba (baseball again) India (Cricket) Pakistan (Cricket) Sri Lanka (Cricket) West Indies (Cricket) Carribean (cricket) South Africa (Rugby and Cricket) Canada (hockey)
India's national game is hockey
This question needs to be more specific. In North America (in general, anyway), "football" is more commonly a reference to a game played with an oval-shaped ball, similar to a Rugby ball. Those outside North America (i.e. the rest of the world) call this game "American football" (AF), which is played in two countries, the U.S.A. and Canada, but with somewhat different rules. Football is the game played with a round ball, generally white. This game is called "soccer" in North America, to distinguish it from AF. Major differences between the two sports are: - number of players per side on the field at once; - equipment worn by players; - number of players on a team; - and too many more to list.
