How are those stats a surprise?
We're a big club - look at all the clubs at the bottom and you can see we're in elite company with a worldwide fan base.
The smaller the club, the more localised the fanbase, that's kind of obvious. I don't even know what these stats are trying to point out.
Careful analysis will allow you to see that Newcastle are high up as everyone in that city supports that one club. All over the top 10 are what I'd define as little clubs - with Wigan being a prime example. The possible exception is Aston Villa which is perhaps the only surprise in that list.
If you have millions of fans are they all supposed to live on the doorstep of the stadium to be valid or something???
The stats that are 100% incorrect are the "People's Club" piecharts. That's just nonsense due to the size of the survey. Whilst the Everton/Liverpool split is ludicrous in itself (the real figure will be around 40/40 with Everton probably shading the fanbase locally), the real telling stat is the United/City split - there's no way at all that City have only a 15% share of the fan base in Manchester. I've been there a few times; there's simply no way that stat is true.
