eli5 Why is population growth not going out of control?

338 views

Why are populations just growing by 1-2% in some nations?
Shouldn’t it grow far quicker if the average couple has 2/3 kids? Removing 25% from those who don’t want kids.
Should people “nearly double”?

Because it takes two people to have a child, your population is only stable if the average couple has two children. And there’s enough people who only have one child, or no children at all to compensate for couples who have more than two children.
