District X, also known as Mutant Town or the Middle East Side, is a fictional location appearing in American comic books published by Marvel Comics. It is a neighborhood in New York City primarily populated by mutants, first seen during Grant Morrison's run on the series New X-Men in New X-Men #127. The ghetto was established in Alphabet City, Manhattan (also known as Loisaida), a neighborhood in the East Village (located between Avenues A to D, and between Houston and 14th Streets). This would fall within New York's 12th congressional district and the New York City Council's 2nd district. According to the front cover of X-Factor #31, it had a population of 743, having been much reduced by the Decimation.
