there are couple of differences between EU and US which can introduce confusion:

1. EU countries sees a lot immigration from Middle East and Africa, who has more kids and there is still a cultural difference towards having kids, give some time to those people to notice the environment and you see similar trend

2. but also EU countries have stronger labor policies which impacts birth rate. Not easy to fire, even when they don't have a job, they get support from government, cheap healthcare (I pay ~250-300 EUR/month for a family, no payment for kids), free dentist until 18 years for kids.

It doesn't cancel what I have said about the impact and reasons, if same conditions exist in EU countries as well, you would see similar decline, which also means this is a political and economical issue

This may well be true. But it also may well be not true to the extend that it can explain that decline in US and the differences to similar countries. So far I’ve not seen much data to back up the alleged causality in much of this entire discussion.

sometimes discussions are just to share the opinion and disagreement, not always they contain result of research. I shared my disagreement about specific statement which says: "This decline cannot be explained by demographic, economic, or policy changes" and shared couple of economic and policy issues which might impact the birth rate.

Real reason(s) could be even different, e.g. chemicals used in foods or a plastic? we need a research. But expecting single reason is probably wrong
