You know, everything is in one city, but each area feels different than the other.
Say, a normal neighborhood: you know is an american place, but in some areas there's a latin sector, and next to it lives jewish or asian. And next to your sector, lots of asian and black people live.
You know, segregated communities in subtext. Everybody belongs to the same neighborhood, but many feel they are from different sectors.
This also can translate to other neighborhoods: say, one area is more patrolled or has more commerce than the other, and the ones in high scale have small patrol posts where officers ask to see your ID. You can walk, but if they find out you are on a list, instead of letting you in they will take you to jail.
