Hello, Classic WoW Forum!
I think it is pretty interesting and useful to see the way realm populations change over time.

These numbers might not reflect the actual population with 100% accuracy.
However, you can determine what is the faction balance and how your server stands relatively to other servers based on this information.
Also, you can see clearly, that once a PvP server doesn’t have any Alliance or any Horde, it tends to lose its popularity - and people tend to migrate to other realms after they themselves have hunted down every opposite faction player to extinction and turned their server from PvP to PvE.
Interesting dynamics can be seen with the rise of Netherwind, Benediction and Earthfury (all servers gained 4500+ raiders) and with the fall of Incendius, Stalagg and Skeram (who lost >1000 raiders over the same period).
