I'm not sure about your calculations, like that 5.4 TFR, but overall the reasoning is correct.
Anyone claiming you need to generate only 2 kids for each family to reach population parity is a drooling retard, every person failing to reproduce adds a burden on the other families to cover up for their failure, or the whole populations shrinks.
Every person have no kids, or only 1 kid, means other families will ahve to birth thsoe 2 or 1 missing kids, that's only to keep population parity, where the entire population doesn't grow nor decreses.
>Fact #1: The total fertility rate required for a population to avoid extinction is 2.7
Remember the important part, human beings are not fractional numbers, 2.7 kids don't exist in nature, it's either 2 kids or 3 kids, and since 2.7 is higher than 2, 2.7 means 3 kids or more
brainlets who don't understand math have issues with this simple fact
