Both Spurs' and Arsenal's fan bases are multi-ethnic, due to the racial diversity in London. In 2002, Arsenal had 7.7% of their fans calling themselves non-white British, rising to 14% in 2008, the highest in the league in these fans surveys. Around 9% of Tottenham fans were non-White in 2008. Both clubs also have extensive fan bases throughout the UK and the rest of the world. Arsenal fans call themselves "Gooners", a term that is derived from the club's nickname "Gunners", which is itself a reference to Arsenal's origins as a munitions factory team.
