District X

District X is a neighborhood in New York which came from Manhattan's rise of the mutant population, coupled with racism among normal humans, which lead to mutants forming their own community. Although humans lived in this neighborhood as well, they were in a minority. However, the neighborhood was quite poor, with a prominent crime rate and warring mutant gangs. Most of the residents regarded it as a ghetto. During the events of the House of M, it was transformed into a rich, exclusively mutant neighborhood named Mutopia X. When the world was reverted back to normal, however, the residents suffered the 'Decimation', and most of them were stripped of their mutant abilities. The remaining mutants mostly moved to a relocation camp on the grounds of the Xavier Institute. Now the former ghetto is the base of operations for X-Factor Investigations.
