I don't think numbers have fallen significantly. However more classes have diluted grids. 10 years orso ago, at a typical club meeting, you had:
Comer Cadet Junior TKM JICA Senior TKM 100C 100A Gearbox
Comer, Junior TKM and Senior TKM all had B Finals. The rest had healthy grids of 15 or more.
Every now and then you had Prokarts, but generally, the 4-stroke crowd were on the fringes (and still are).
Now:
Comer Cadet* WTP* Honda Cadet* MiniMax Junior TKM Junior Rotax Senior Rotax Senior Rotax Heavy Senior TKM Gearbox +Some regional variant like Blue, or TaG
Very few clubs have any classes (except perhaps Cadet Libre) that have B Finals.
Incidently, TKM, when popular, had the reputation of being the "nutters" class. A bit like the reputation of Rotax now.
TKM's only problem as a class is that it missed the boat. Once the grids have gone, it's almost impossible to get them back. I think TKM is by far the most superior class. It's cheap, it has better power delivery, it requires very little maintenance, the balance of grip and power is spot on etc etc. However, it didn't respond to a changing market and lost out for it. That market isn't one I'm interested in racing in (Rotax), but the masses are, so that's were the grids are.
Easykart is the modern TKM, but without club grids, without chassis choice and without open but limited tuning. Everything else about it screams of what Tal-Ko should have done 10 years ago. More modern chassis rules, 125cc high powered air-cooled TaG and tyres to match. They're trying to do it now, but I fear they're too late.

PS Air-cooled, piston ported, clutchless engines are still the essence of karting. It's a shame so few agree.
