The increase in the number of people who do not belong to any religion (“nones”) has long been observed in many societies in the Northern hemisphere. This process is already well advanced in East Germany, where the proportion of “stable nones”, i.e., those who grew up without any ties to religion from childhood onwards, has become particularly large and will most likely form the majority in the near future. Given the sociocultural relevance of this group, it is worth taking a closer look at them. In this paper, we examine how far they differ in terms of their familial religious conditions of origin and their present-day religiosity from the nones who still grew up in a religious-denominational tradition (“leavers”), and also from those who still have ties to a denomination (“affiliates”). Finally, we discuss the consequences for the future development of the religious field that arise from the fact that the group of “stable nones” will constitute the majority.
