For the last 30 years, the question of religious mobility has generate
d increasing division and controversy among social scientists. This is
particularly the case among sociologists of religion, where an on-goi
ng debate concerning the expected growth in conservative Protestant ch
urches at the expense of their more liberal colleagues has dominated t
he literature. Using recent data from both Great Britain and Northern
ireland and employing a technique of analysis not hitherto adopted in
the religious mobility literature, this paper examines the nature and
extent of religious mobility within the UK. The results suggest that,
whereas the majority of church members never change their religion of
origin, for the religiously mobile, religious disaffiliation is by far
the most common outcome.
