It takes two people to have a baby. Specifically it requires a man and a woman… anyway, I don’t think this is the time for that talk. So everyone who has children needs to make 2 children to keep the chain going.
However, sometimes people don’t have children. They might just not ever decide to do so, or they might die, or they might be infertile or sterile, etc. Whatever the reason some people won’t have offspring and those that *do* have offspring will need to make up that slack to keep the population stable. On average that is generally understood to be the 0.1 births.
