Re: [Frodo] How many BASErs are there?
I think this question is terribly dependent on the definition one chooses for a "BASE jumper."
On one end, I estimate that perhaps 5,000 folks alive today have made a BASE jump at one point in their life. This may be on the high side, but not by an order of magnitude.
On the low end, I'd say there are probably less than 200 people in the world who are really experienced enough to open a wide variety of new objects by themselves, and who are up to speed on most all current technical trends in modern BASE. In actuality, I'd guess this number to be closer to 100 worldwide.
In terms of jumpers who have proven capabilities across a wide swath of the sport (from low freefalls and subterminal aerials to big walls and tracking skills, along with object opening experience across the BASE categories, through the more arcane skills of object acccess and other "cloak and dagger" techniques), probably around 50 or so worldwide. In other words, as the sport develops further we are having more and more folks who become specialists in one area, primarily.
The days when, say, Dwain has been at the top of areas of the sport ranging from ultra-low freefall through aerials and subterminal tracking are fading. No mere mortal can be the best at it all nowadays (though Dwain is no mere mortal, clearly). Similarly, there's really no climber who is at the top in sport, trad, bouldering, aid, mountaineering, technical mixed, etc.
While "Europe" (including the Scandanavian countries) isn't technically a country, there are probably more folks jumping in Europe on a quasi-regular basis than everywhere else in the world combined. As one example, there's 30 folks jumping pretty regularly in the city of Antwerp alone. . . extend that out all through Europe, and it's lots of folks. Many aren't active online, but they are jumping - alot.
I'm hearing that there are many new jumpers coming up through the ranks in Russia nowadays. Dozens. If those jumpers continue, and in turn train more jumpers, that could be a huge group of jumpers in a few years' time.
Australia has given so much to the sport in terms of technical advancement, attitude, and plenty of super-talented jumpers. However, in pure numbers I don't think there are that many active Aussie jumpers. . . at least compared to Europe or the USA.
America has plenty of jumpers, but not many who make it past the "do a few (dozen) jumps from a few existing objects" category. Nothing wrong with that, but I just don't think the American spirit circa 2003 is really breeding lots of really top-end BASE folks compared to other areas of the world. This is, of course, not to say that there aren't many super talented American jumpers (present company excluded).
I've heard that the substantial majority of several gear manufacturers' sales is - and has been for years - to Europe and Scandanavia.
Of course, all of the above is simply one canine's biased opinion, nothing more.
