Why do more people of both genders wanting kids still override those with NO desires?

A while back, my friend did a short personal written survey and then converted it to an overall %. Nearly a 90% of women wanted kids versus just 10% without any desires for them. In men, it was a nearly 75% wanting kids vs a 25% not wanting them. 75% is still more than half; that still means a majority.

It should be 50/50 but nope, more people of both genders desire kids. They still override those with no desires or that hates children. Why?
