Impossible to know many active members are on CS, but searching for recent logins shows poor results in most locations (recent logins < 6 months/reply rate). BeWelcome.org has 200,000 members, and do a annual clean up, that turns profiles with non-functioning email address/ lack of logins to inactive in search. 200,000 means you are likely, when using the right approach (personalized messages, full profile) find a host in most locations. Of Couse, no paywall/ no ads/ no verification fee/ registered charity/ volunteer based are the bonus points.

A partial answer based on, well, claims on the CouchSurfing subreddit and other gossip here-and-there:
Finally, one needs to remember than the number of CS users was likely inflated. That is, many accounts were likely tombstones; and I've heard it argued that quite a few account were bot-created, although I haven't seen any evidence to support this claim. It is not easy (for me) to estimate how many active users CS had when it had 12M registered users overall.
