Often people look at Birth Rates & Fertility Rates alone without looking at Replacement Rates & their relationship; assuming it's always 2.11 (West RFR).
Birth-rates even when compared to death-rates don't give a true picture of trajectory as it doesn't account for whether those deaths are pre or post reproductive years. This is why TFR coupled with RFR (accounts for full range deaths) is a better measure.
TFR is measure of successful reproduction & RFR is the TFR required to maintain a population level. While it is blackpilling to see Africa with 5+ TFR, this is less concerning when their RFR often exceeds 3.5 leaving a 1.5 NFR (net) & minimum –3.5 NFR.
The higher the RFR, the lower the NFR can possibly be; so 3.5 RFR will decline 1.4 TFR faster than 2.1 RFR if both countries are equal or even 0.
A good example is the Philippines, with 2.7 TFR but 3.0 RFR which actually declines more than European nations with 1.8 TFR.
This gives Whites a leading edge when global TFRs race to zero.
