Not hard to figure out: The difficulty in making ends meet with only one wage earner, the emphasis on women developing careers rather than being a mother, the social pressure against families, particularly large families, birth control availability/abortion, and maybe a realization that parenting is difficult and these latest generations don't like "difficult".

Coupled with the emergence of large numbers of non-reproducing homosexuals and you have the perfect formula for self-extinction.

Luckily we have floods of "immigrants" coming in to take over.

I guess it's a mystery to demographers who want to be published.

Agree whole heartedly agree with every point you made.

Permit me to suggest an additional cause:

Boys raised by women do not always learn how to be men.

Men become fathers, boys become baby daddies.
