I think we are losing . . over all.
Although I don't have empirical evidence of it.
The best way to get information may be to contact the major umbrella groups.
Nicindy.org
and

Otherwise you probably have to contact each organization individually . . .
But you could do it pretty quickly with emails . . . in about 10 minutes.
