Hi brewer,
If the fertility rate is less than 2.1, then the group being measured will not maintain the population size.
For our audience at home, here’s a site that seems legit to learn about the difference between the two. Birth Rate vs. Fertility Rate For example, they say

I know this is incorrect.Nowhere did I claim that fertility rate and birth rate were the same. I think you are referring to this exchange.

Yes, abortion reduces the birth rate. It also reduces the fertility rate, which is the number of live births per woman. That’s how the UN, demographers, and others (probably sociologists, too!) who study this define it.bold mine: Then they are incorrect. But it's my guess and I find it more likely that you are incorrect. Please provide the link for your UN quote.
Unless you are arguing that abortions directly impacts future fertility status. If you are, that would be incorrect also.

Once I understood, I would be happy to post the source. I want to answer the question you are asking, though, and it wasn’t clear. This current exchange makes it obvious that we were reading that in two different ways.
Then you want me to do the work that you should have done to make the claim. Sorry, that's on you to support your claim.

Pew Research Center Wrote:The global fertility rate is expected to be 1.9 births per woman by 2100, down from 2.5 today. The rate is projected to fall below the replacement fertility rate (2.1 births per woman) by 2070. The replacement fertility rate is the number of births per woman needed to maintain a population’s size.

Quote:While birth rate provides a snapshot of the number of births occurring in a population, fertility rate gives a more comprehensive understanding of the reproductive behavior of women.
