MEG is around 0.008% of the total Backrooms population.
A comparison I like to make is Tiktok.
41% of the world doesn't have internet access. It would be more like 98% in the Backrooms, but you have to keep in mind that there's also around 1000 times as many people in the Backrooms.
Tiktok is just an app that people enjoy, and it has 1 billion members.
MEG controls almost the entire internet, restricts lifesaving information and supplies from people who haven't joined them, have a few legitimate bases where people are born, and patrol most safe finite levels, and has a little over half of that.
600 Million is a very conservative number all things considered.
It's also important to note that of this 600 million people only like 2 million actually live in MEG bases. The rest only see members of their group 40% of the time and no other MEG members, with the only interaction being through this database.
