Reddit contains more than 3 million subreddits/communities.
You can find a subreddit for every topic in the world.
However, only a few of them has the maximum number of members.
It means that there are a lot of most popular subreddits that contain more than 1 million members.
Most of them are available for many years.
I have added a list that has the top 25 most popular subreddits/communities on Reddit (all of them added as per their popularity).
