You need to go to a consistent and comprehensive source, like the CIA Factbook. Additionally the website, Index Mundi, has accumulated many years of CIA Factbook statistics.
Most demographers don't use that same methodology on fertility rates which is based on all women of all ages and includes a fudge factor based on untimely deaths. Nobody actually knows what the untimely death rate is. They use the 0.1 as in 2.1 but it could be more or less than 0.1.
Instead, demographers use or define the fertility rate as the birth rate of women of child bearing age
And it is not just the fertility rate that is important. Russia has a negative population growth rate while the US has had a pop growth rate of O.9 to 1.0 percent per year for many years, which they achieve with a birth rate plus immigration rate minus a death rate.
Canada has the same pop growth rate as the US which they achieve with a lower birth rate than the US but a higher immigration rate than the US.
Mormons got it right! Lots of babies! The full quiver idea. Well, I read that women who have babies and breast feed their infants have fewer instances of breast cancer! Having children makes one less selfish too. Let minorities do the abortion thing!
Lots of Russians seem to be coming to New England. Personally, from what I have seen of their women, I think they should bring even more over.
