Answer
I feel that the average age of ramp skaters is about 15 years old. There are not very many good ramp parks in the US. Due to insurance problems many open and close up quickly. The popularity has increased some with the X-Games on cable TV the past few tears. I do not know how many ramp skaters there are in the US. The international association is called International Inline Figure Skating Association. http:/www.iifsa.com You might also try looking on the "RSWEB" site and "aggressive skating" on a search engine.
