Population decline is now a serious consideration in Western Europe, the US and North America, Japan, China, and several more countries. In fact, the only countries where the population replacement rate is functioning at a needed, typical level, are several Sub-Saharan countries in Africa, Egypt, and a few countries in the Far East. Why is this happening? Why are people rejecting the idea of more children and families? And why does it matter that population decreases in countries over time, i.e., fewer children, fewer young adults, even as people live longer into advanced years? It's not biological but philosophical or religious, but why? What are the religious worldview underpinnings of this decline and is it biblical?
