Corporate Special Administrative Regime

The Corporate Special Administrative Regime or CSAR (pronounced SEE-zər) is a type of administrative authority in the Terran Federal Republic. It is applicable to star systems, planets or entire star sectors. When applied to planets, it is known as a charter. CSAR areas have most services provided by the federal government or commonwealth administrations replaced by corporate ones. The most important one is security and law enforcement. Around 23% of all star systems in the Federation are under CSAR, although a majority are uninhabited. This accounts for over two billion people in the Federation living under CSAR administration. 
The most populated CSAR system is the Aleph system with a population of over 400 million and with the world of Halcyon alone housing 200 million people. C2I alone accounts for 46% of all CSAR systems whilst the ALEPH group's members account for over 87% of systems and 99.34% of the CSAR population.
