Supplementary material: The dynamics of social group competition: modeling the decline of religious affiliation
نویسندگان
چکیده
The model presented in this paper is applied to the widespread phenomenon of religious shift, but may be more generally applicable to a variety of competitive social systems. The model allows for either competitive exclusion (a ≥ 1) or stable coexistence (a < 1) in systems composed of two social groups, and makes sense in the context of social networks. A similar model (reference 1) was applied to the phenomenon of language death. Some other competitive social systems in which identical or very similar models may apply include, for example, smoker vs. non-smoker, vegetarian vs. meat-eater, obese vs. non-obese, and Mac user vs. PC user.

Dynamics of social group competition: modeling the decline of religious affiliation.
When social groups compete for members, the resulting dynamics may be understandable with mathematical models. We demonstrate that a simple ordinary differential equation (ODE) model is a good fit for religious shift by comparing it to a new international data set tracking religious nonaffiliation. We then generalize the model to include the possibility of nontrivial social interaction networks...
متن کاملA mathematical model of social group competition with application to the growth of religious non-affiliation
When groups compete for members, the resulting dynamics of human social activity may be understandable with simple mathematical models. Here, we apply techniques from dynamical systems and perturbation theory to analyze a theoretical framework for the growth and decline of competing social groups. We present a new treatment of the competition for adherents between religious and irreligious segm...
متن کاملHomophily and competition: a model of group affiliation
How can we understand the interaction between the social network topology of a population and the patterns of group affiliation in that population? Each aspect influences the other: social networks provide the conduits via which groups recruit new members, and groups provide the context in which new social ties are formed. While many social simulation models exhibit group formation as a part of...

How can we understand the interaction between the social network topology of a population and the patterns of group affiliation in that population? Each aspect influences the other: social networks provide the conduits via which groups recruit new members and groups provide the context in which new social ties are formed. Given that the resources of individuals are finite, groups can be conside...
متن کاملBirth Cohort Changes in the Association Between College Education and Religious Non-Affiliation
This article examines the changing association between higher education and reporting no religious affiliation in the United States. I argue that increases in higher education have led to a decline in the individual-level effect of college education on religious non-affiliation. Results from hierarchical age-period-cohort models using more than three and a half decades of repeated cross-section...
