Supporting Information:
- Trend Analysis: Recent trends indicate a rise in the religiously unaffiliated population in developed regions such as the United States and Western Europe, where secularization is linked to higher levels of economic development and educational attainment. 
- Demographic Dynamics: Contrastingly, the religiously unaffiliated demographic is shrinking globally due to lower fertility rates compared to religious groups, especially in developing regions where religious populations are growing rapidly. 
- Regional Variations: Highlight how regional differences could affect this trend, with areas like Sub-Saharan Africa experiencing rapid population growth among religious communities, potentially offsetting increases in the unaffiliated demographic in more secular regions. 
Potential Outcomes:
- A continuation of the growth trend among the unaffiliated in more developed, secular regions. 
- A global decrease in the unaffiliated share due to high fertility rates in religious regions. 
- Stable or nuanced changes influenced by political, social, and economic factors.
