HUMAN WORLDS

Most human colonies were small, populated by well under one million people, while a few were very large, with a population in the hundreds of millions.

 
 

 

ALL HUMAN WORLDS

Prior to the start of the war with the Covenant, humanity had established colonies on around 800 separate worlds.  The war took a massive toll on human colony worlds, particularly those in the outer colonies.  By 2536, most outer colonies were destroyed, leaving only a handful of small colonies to fend for themselves.  Of those, only an even smaller few managed to survive the war unscathed.
