Combining theoretic approaches in the sociologies of religion, of organizations and of migration, the project seeks to contribute to theory-building on religious accommodation and the negotiation of secularity. It does so by creating a dataset accounting for cross-national and cross-organizational differences in religious accommodation. The project is based on the assumption that the concept of organization-specific approaches to the negotiation of secularity can theoretically and empirically complement ideas about a nationally defined relationship of state and religion. It is also assumed that cross-organizational differences are systematic and thus can be explained. Using theories to build typologies of organizations that for example take into account an organization's relationship to the environment, its hierarchy structure or its relationship with a broader public, the project seeks to explore which organizations find similar solutions to issues of religious accommodation across countries and also asks which organizations are more likely to be in line with or deviate from the official regime of state-religion relationship. To explore these questions and hypotheses, the project collects data on seven indicators of religious accommodation (e.g. chaplaincy, prayer spaces) in five to six organizations per country for a historically established religious majority, a historically established religious minority and an immigrant religious minority. The dataset will cover a maximum of 30 countries at one point in time.
