That's pretty characteristic of WT/WC here in the States too. Same for FMA (eskrima, arnis, kali), at least in my area. But the overall numbers remain small. On the other hand, TKD is huge with kids, and BJJ is getting increasingly popular with older youth and young adults from around 16 - 24 years of age. At least that's my impression (no factual data).
The other day I read a post somewhere that dismissed WC as an "old man's art". Ironically, being an old man (at least compared to the poster) I took no offense at all. Boxing and grappling are not arts intended to be practiced for your whole life. There are some inspiring exceptions, but they are rare. On the other hand, when my WC finally fails me, I'll probably just fall back on eskrima and start whacking at people with my cane! :uhyeah:
