Does society accept couples who don't want children?

I read many posts here where young couples don't like the idea of wanting a children and some don't even plan to marry but I have seen some older couples in their 50s or 60s who didn't have children but society I don't know judges them and says look at them. All stress free and enjoying life. And some say that lady cannot get pregnant. Making all sorts personal judgement of one and another. It's crazy
