Since the early colonial period, the city has been organized into eighteen barrios or neighborhoods. The pre-Hispanic city had official neighborhoods, called "capullis", which the Spanish reorganized around parish churches, each with a patron saint. The official chronicler of the city, however, still refers to the neighborhoods by their pre-Hispanic term. Eight of the barrios are located in the municipality of San Andrés and ten are located in San Pedro. The neighborhoods of San Pedro Cholula are San Miguel Tianguisnahuac, Jesús Tlatempa, Santiago Mixquitla, San Matías Cocoyotla, San Juan Calvario Texpolco, San Cristóbal Tepontla, Santa María Xixitla, La Magdalena Coapa, San Pedro Mexicaltzingo and San Pablo Tecama. The neighborhoods of San Andres Cholula are San Miguel Xochimehuacan, Santiago Xicotenco, San Pedro Colomoxco, Santa María Coaco, La Santísima, San Juan Aquiahuac, San Andresito and Santo Niño. Most of these barrios have a patron saint's name followed by the indigenous name (from the Nahuatl language) that remains from the pre-Hispanic period. The neighborhoods closest to the center are urbanized, with those on the edges of the city maintaining more of their rural character, with economies based primarily on agriculture and brick-making. The main unifying factor of these neighborhoods and municipalities is a complicated framework of regular cyclical social events, which are sponsored in rotation among the various barrios. Many Cholutecans still use their pre-Hispanic surnames, such as former town stewards Raymundo Tecanhuehue and Humberto Tolama Totozintle. This is because a number of members of the old Indian nobility were allowed certain privileges after the Conquest.
