I was listening to a podcast about the falling birth rate and began to think of friends and family members that haven't had children. I would honestly say that the majority had the desire to have children at some point but ended up without children either due to medical or fertility issues or more commonly life circumstances.
For the women I know, it was almost as if they suddenly ran out of time and found they had fertility issues when they decided they were ready for babies (usually mid/late 30s) or they either didn't have a partner or their partner didn't want children. I know lots of people actively choose to not have children but I would say this is uncommon amongst the people I know. I'm therefore wondering if my circle is unusual or is unintended childlessness a much bigger thing than we are led to believe?
