Polo statistics and literature

I'm going to go through the "In the news" thread for bits and pieces. But I was wondering if anyone has previously published any statistics about bike polo?

Things I'm looking for:
Number of bike polo countries (rough size of sport) since 2006 onwards?
Number of worldwide bike polo players annually since 2006 onwards?
Number of UK bike polo players annually since 2008 onwards?
Anything else like this...

Also, has anyone published anything comprehensive in terms of the history of the sport, the movement/growth of the hardcourt version over the last 8 years, etc?

Any help much appreciated, the info is for a London Open sponsorship pack and will be made widely available again once collated/published. Cheers.

History:
History of hardcourt
History of bike polo
Polo movement/development by city

Number of polo players:
