From 2,997 active users across all lemmy instances at the beginning of June, the number increased to 52,797 by June 30th. Source.
An active user on Lemmy is "someone who has posted or commented on our instance or community within the last given time frame.” Source. That means lurkers are not counted as active users. There are currently almost 200k total users spread across the top 10 non-bot lemmy instances.
We’re really building something here!

I had heard about it for a week, but finally signed up when a mod I trusted on a reddit sub I used posted a sign-up link to lemmy.world. I’m somewhat tech proficient, but that extra step of figuring out a good instance to join was enough to stop me for a while. I didn’t want to join a dud and have yet another dead login somewhere. YMMV, of course!
