We're seeing an increase from 53k active users at the beginning of July to 72k active users at the time of this post.
According to Lemmy's documentation, an active user is "someone who has posted or commented on our instance or community within the last given time frame.” Lurkers aren't considered active users, so basically these are content creators on Lemmy.

A community to talk about the Fediverse and all it's related services using ActivityPub (Mastodon, Lemmy, KBin, etc).

While there is definitely a bunch of content popping up now thanks to to influx of actuve users, there still are some more niche communities that were pretty active on old reddit that i guess just can get to critical mass on lemmy and so are pretty dead. I hope that can change going into the future though.
If the community you're looking for exists but doesn't contain posts, the best thing you can do is to start posting yourself, no matter the quality you think your content has.
Humans tend to follow others, which leads to both positive and negative feedback loops. If nobody is posting, anyone discovering the community will think "oh this place is dead, no point in posting".
Being the first to break the ice and do something in a group setting is scary, but once somebody is doing it it's much more likely others will join in.
It's often uncomfortable to be the first person to start dancing to the music, but have you noticed how much easier it is for everyone else to join in when that one guy starts going off?
That's a great way of looking at it.
