Wherever I look at general, completed, and total fertility rates are below replacement rates for US. Do you have any source on this positive natural rate of increase?
- dragonwriter 10y agoFertility rate below replacement isn't the same as not having positive rate of natural increase; like you, I find every source on fertility rate has it below replacement, but every source on natural increase has it positive. [0] That's entirely consistent; below replacement fertility doesn't imply a current negative rate of natural increase, though if maintained indefinitely it implies an eventual negative rate of natural increase.
