Background It is estimated that around half of American adults have changed religion or denomination at least once, yet little is known about the effect of different motives on these changes. Purpose This paper seeks to understand the motives driving religious change and the relationship between the reason for religious change on the nature of that change, be it denominational switching, conversion, or disaffiliation. Methods The data come from the Pew 2007 Religious Landscape Survey and 2008 Conversion Recontact Survey. First, reasons for changing religion are presented, followed by a series of binary logistic and multinomial regressions that analyze religious changes, their motivations, and justifications. Results Among the many reasons for changing religious affiliation, motives directly associated with personal aspects of religion are much more commonly cited than mundane rationales, such as marriage or geographic mobility. Disaffiliates are more likely to view their religious change as being motivated by personal religious concerns, whereas denominational switchers and, to a lesser extent, converts tend to cite mundane motives. Conclusions and Implications Decisions regarding affiliation are the most likely to be attributed to personal religious motives, either in an attempt to justify actions to family and friends who have remained religious or because affiliation and non-affiliation are perceived as religiously distinct. Denomination switching and conversion are associated with mundane motives, perhaps due to the rise of religious pluralism, which asserts the validity of a range of religious options, reducing the religious significance of denominational switching and conversion. Thus, personal religious motives play a role in deciding whether to consume religion as a product, while choices regarding a particular brand of religion are attributed to more mundane concerns. This paper adds to our understanding of the interplay between secular, communal, and personal religious motives in shaping religious preferences. In doing so, it sheds light on the nature of such decisions and the broader religious landscape. Additionally, it may provide insights useful to religious leaders on how they might best attract new affiliates.
