This should be for France:Didn't the Baby Boom make up the population losses of WWII (and then some) for all the countries involved? Vietnam and Cambodia also suffered massive casualties in their wars but their populations now are greater than ever before.
I do agree though that if Africa had suffered a population catastrophe a century ago, it would not have its present population, as it would still have massive growth but a lower starting point.
WW1 doesn't seem to have recovered that much, but WW2 seem to have risen above previous birth rates, but that's more correlated with the economic boom, considering even Sweden was affected by it.
Neither Vietnam nor Cambodia suffered 75% casualty rates and neither was my point that it couldn't regrow back, just that it would be lower than it otherwise would have been, in the case of both these countries, the war and the genocide set them back in the implementation of birth control or of the demographic transitition but that isn't really the case for this Subsaharan Africa which mostly is still quite on the first 2 stages(outside the South and some exceptions)
