Which would of course also require a collective form of prenatal sex selection
If the goal would be to have a stable population size but with fewer births per woman, I think a collective form of prenatal sex selection (of the kind I describe above) would work.
What this sex selection would look like would be another issue. Whether externally fertilized embryos are selected before they are placed in a womb, or whether it would involve forms of abortion (or even infanticide): it’s up to your imagination.
But there are no lies, nor any misapplied statistics?
