Area

An Area is a Britannian term for a conquered nation or group of nations, each distinct Area being given its own distinct number and ruled as a colony. It is believed that there are at least 18 areas in existence, numbered in order of conquest, though only a handful are mentioned by name. Following Lelouch's ascension to the throne, he abolishes number area system

Known Areas

 * Area 11 - former Japan
 * Area 18 - former Middle Eastern Federation
 * Area 10 - former Indochina

Numbers
Just as each sector is given a number, the natives of the region are referred to by the same number. Hence, Japanese become "Elevens" and natives of the Middle East, regardless of their ethnic group, become "Eighteens but Britannia minimally rules region because there are affairs they do not want to get involve in".

Collectively, all Non-Britannians living within the Empire as referred to as the "Numbers", which many Britannians try to separate themselves from. Many Non-Britannians find this very offensive, and the Empire probably uses it as a form of cultural suppression. The term Numbers in itself is often used derogatorily by Britannians.
