> how many of those people over 30 still desire children but tried and failed, and then tried IVF and failed (or couldn't afford it), and/or tried adoption but couldn't afford it or failed
You're also missing some big ones:
- people over 30 who have overly busy work schedules that prevent them from dating even though they want a partner and possibly kids
- people over 30 who really want a romantic partner but can't find anyone who likes them, or lack the skills to engage in a healthy romantic relationship
- people over 30 who for career reasons are stuck in a place that likely does not have any compatible partners within reasonable distance
- people over 30 who want kids but aren't financially ready and voluntarily not having kids until/unless ready (but would if they suddenly make bank at 35).
