Note: The difference between worlds and systems comes from two counts. Systems with a distant stellar companion count as "double systems", and thus count as two worlds, but only one system. Systems where the population of a second body within the system is within 0.1% of the main world also count as "double systems", accounting for two worlds, but only one system each. With these two factors accounted for about 25% of the systems count as doubles, adding to the number of worlds within the Imperium.

History & Background (Dossier)

In addition, the expansion of the Imperium since 420 had added many new worlds that had to be included.
