Alpha Centauri: Open Skies, Hidden Depths
A habitation complex is a megastructure built primarily as domiciles for a very large amount of people. Featuring an extremely high local population density, habitation complexes have been argued by some to be examples of arcologies in and of themselves, rather than the sub-arcologies as which they’re usually viewed. Opponents of this classification, however, usually argue that the term does not apply, given the complexes’ lacking self-sufficiency.
In spite of their high efficiency, both with regards to material and energy use, the use of habitation complexes has faced widespread criticism from sociologists, who, citing studies showing severely heightened crime rates and extreme poverty in such locations, argue that the concept should be outlawed or highly regulated.
