West of the Historic Center (Centro Histórico) along Paseo de la Reforma are many of the city's wealthiest neighborhoods such as Polanco, Lomas de Chapultepec, Bosques de las Lomas, Santa Fe, and (in the State of Mexico) Interlomas, which are also the city's most important areas of class A office space, corporate headquarters, skyscrapers and shopping malls. Nevertheless, areas of lower income colonias exist in some cases cheek-by-jowl with rich neighborhoods, particularly in the case of Santa Fe. COUNT 4
