DMT: The biggest reason for declining birthrates is that having children has become an economic disadvantage for individuals

People often explain declining birthrates by pointing to changing values, feminism, dating culture, or people becoming less interested in family life.

I think those explanations miss the bigger picture.

For most of human history, having children was not only a personal choice but also an economic decision. Children helped with family labor, supported parents in old age, and contributed to household survival.

In modern developed countries, that calculation has almost completely reversed.

Raising a child now often means hundreds of thousands of dollars in expenses, years of childcare costs, larger housing needs, and potential career sacrifices. At the individual level, having children has become one of the largest financial commitments a person can make without any direct economic return.

This seems like a major reason why birthrates have fallen across very different cultures. Countries with very different beliefs, religions, and social structures have all experienced the same trend as their economies developed and children became more expensive to raise.

Policies like paid leave, childcare subsidies, and family benefits can reduce the burden, but they are mostly trying to make having children less costly. They do not change the basic reality that children are no longer an economic benefit for most individuals.

If society wants higher birthrates, I think the conversation should focus less on convincing people to value family more and more on understanding why the economic incentives around having children have changed so dramatically.
