The Arabian/Persian Gulf region is home to some of the fastest-developing cities in the world. In my research into these new hubs of global capitalism, one issue I examine is the role of Catholicism. While official statistics on foreign populations are not available, estimates from various sources (including embassies and churches) place the Catholic population in these cities at — astonishingly — between 10-30 percent, with a contributing factor being the increasing Filipino emigration to cities such as Dubai and Doha. One crucial way Catholicism shapes modern life in the Gulf is by serving as a source of “technical” competencies or cultural capital—technical in the sense of having to do with techniques, skills, and practices that contribute to economic outcomes and social mobility.
