Diferenciación socioespacial en la Zona Metropolitana de la Ciudad de México Enrique Pérez Campuzano Clemencia Santos Cerquera Ciencias de la Tierra Segregación Índice de Moran Zona Metropolitana de la Ciudad de México En los estudios urbanos la diferenciación socioespacial es uno de los temas recurrentes, sin embargo, existen pocos estudios en América Latina. En esta investigación se describe la segregación socioespacial en la Zona Metropolitana de la Ciudad de México (ZMCM) y se utilizan variables demográficas y de vivienda del II Conteo General de Población y Vivienda, 2005, para establecer la diferenciación interna. Los resultados indican la existencia de segregación al interior de la ciudad, identificándose una herradura que va del sur al poniente y un sector al norponiente que presenta los mayores niveles de consolidación, un anillo intermedio con una mezcla social y una periferia con los mayores rezagos. 2011 artículo científico 0188-4611 https://www.redalyc.org/articulo.oa?id=56919176008 es http://www.redalyc.org/revista.oa?id=569 Investigaciones Geográficas (Mx) application/pdf Universidad Nacional Autónoma de México Investigaciones Geográficas (Mx) (México) Num.74
