I don't think this is disagreeing with my questions? Nor do I think I'm disagreeing with folks that make these choices. If someone wants to take efforts to make sure they never have children, I think that is something they should be able to do.
My question is if there is no actual contradiction between the polls of how many childless people don't want children, versus how many people with children consider it a defining facet of their lives?
I'd be interested to know how people would have polled on those questions throughout the decades? Fertility rates would tell us how many people are acting on having kids. But it would not let us know how many people that are happy with kids today were saying they did not want kids in the past. Would it?
