In this unique analysis of Muslim population shifts in the Western world, geographer Barry A. Vann provides fresh insights into the theological factors that play into these demographic trends. Vann examines the "imagined geographies" of Muslims with a puritan orientation. People with this mind-set are little inclined to accept a pluralistic, multicultural, live-and-let-live concept of society. And conflicts between conflicting value systems are almost inevitable.Vann notes that this purist approach to Islam is certainly not universal among Muslims, and there are many varying interpretations that are more moderate in outlook. Nonetheless, the undeniable theological background of all Muslim communities colors their values and attitudes, and must be taken into consideration when attempting to understand the potential conflicts between contiguous Muslim and non-Muslim groups.Given the fact that the population of Muslim immigrants is growing in traditionally Christian and increasingly secular countries of the Western world while the resident populations are either stagnant or declining, Vann's insightful analysis of the ways in which Islam influences perceptions of community and geography is of great relevance.
