[[File:Deployment Screen.jpg|thumb|View of sectors.]]
Sectors is the title given to certain areas of the map. e.g. The canteen and kitchen area is one sector (as shown in image on right)
Each sector is colour co-ordinated.
Since Alpha-2 version of the game, the primary use of sectors is to assign guards in the [[Deployment]] window.
Sectors are broken up inside of a building by doors - if you have multiple rooms that flow into each other without a door, they will all be considered one sector. Jail doors do not seem to count towards this, but large jail doors and normal doors do.
Since [[Alpha 6]] you're now able to dedicate cell blocks to maximum security,
minium security or general population
