During the last 20 years, the number of people who are religiously unaffiliated in Norway has increased considerably, from four percent in 1991 to 14 percent in 2012. Using Norwegian survey data collected in 2012, I examine two aspects of the religiously unaffiliated: i) their social characteristics compared to the religiously affiliated and members of the Humanist Association, and ii) the predictors of unaffiliation using logistic regression. The results show that the unaffiliated are younger and include a larger proportion of individuals with a higher education than the religiously affiliated. Their social characteristics are often placed in between the affiliated and the humanists, suggesting a multifaceted social category. Certain factors, such as having had an unreligious upbringing and having friends with different religions, are highly predictive of unaffiliation. The most influential factor is rejection of a God or a higher power. Surprisingly, gender is insignificant in predicting religious unaffiliation in Norway. Possible interpretations are discussed.
