I've said this before but some of those stadiums are at full capacity. And we're talking 12 teams in England compared to 5 here. And 14 1st division + 12 2nd division in France.
Arguing that they have worse crowds than us is pretty dumb. They support their teams much better. Look at the Tests which sell out. Looks like 80% of the clubs have improving numbers too. Game is in real good shape over there.
There is actually 16 teams in the D2 and the English 2nd tier gets ok crowds also.
The main thing about those crowd figures is that rugby really is a fringe sport in comparison to football in Europe.
Also many of the cities and towns on the list are pretty small - take Leicester for example just over 300k there and they have a team in the EPL also, Toulon is about half the population of that.
Clubs in Europe are generally very well supported by the areas for what they are.
France and England have clubs not regional teams like here thats the main difference - while Ireland have regional teams they always have and people identify as an Munsterman for example and love the team.
Wales and Scotland have suffered due to these new regional sides and crowds are poor - hats off to Glasgow though they are doing well and for most things are improving.
That being said Edinburgh has 500k and we get crowds of just under 5k while Sydney has 4.5 million and got just over 17k two seasons ago.
