Religion and Migration around the Globe: Introducing the Global Religion and Migration Database



International migration is a global phenomenon involving nearly 215 million people, equivalent to 3% of the world’s population. Previous databases of global migration catalog international migration using a variety of variables (sex, education, age); however, religion is rarely addressed within these data sets. Representing nearly half a million data points, the Global Religion and Migration Database (GRMD) was constructed – the only global database estimating the global migrant population (stock) by origin, destination, and religious affiliation. This research note serves as an introduction to the GRMD, detailing the construction of the database and providing key findings from a global perspective.
