Why is it so difficult to find a CF (Childfree) woman for marriage?

Hello all, I'm a guy in early 30s, and I'm trying to find a Child-free (CF) woman in the 28-34 age group for marriage, doesn't matter whether she's never been married or is a divorcee, as long as she's honest about the reasons. I'm wondering if the pool I'm looking at is just too small, or if the CF and DINK (Dual Income, No Kids) lifestyle is still not that common in India. Looking for insights, thoughts from women specifically. Thank you. PS: Child-free woman is a woman who doesn't want to have children.
