Sector

Definition

A sector is an administrative and transit region inside the Star Wars galaxy that groups together several star systems.

Why it matters

The Republic and the Empire run politics, taxation and military command at the sector level. Whoever controls a sector controls trade routes, populations and garrisons.

Practical use

Phrases like Outer Rim sector or Mid Rim sector help locate film and series settings — which worlds are politically grouped, and which are pushed to the periphery.
