This is a good thing: it means women are more likely to be able to choose when they start their families, and the size of their families.

Where I am, it means women are less likely to be able to choose either, and really I don't know any country where the above holds true. I wanted to have my first child at 22, and at least 3 children. I'm now over 30, still childless. And we know it isn't just me because there was a cautious increase in births during the brief fat years. People (men and women) want an "intellectual heir" of sorts, not to have the woman carry a baby to term and pay a stranger to neglect it while both of them work full-time.

It if of course not up to the women to correct the birth slump. But the current situation is emphatically not good. It is not good that people "choose" not to have children because they (correctly) think having children isn't rewarding, it's a civilizational crisis.
