I'm surprised at the surface difference between birth and death rate because we're told the aggregate rate of increase is declining. The difference between the two suggests birth outruns death by 2:1 which feels steep for something which will max out in 2050.

I realise sub-saharan Africa continues to be high birthrate and is a huge component of world population, but the trend of increased economic activity to lower birth rate is really high worldwide, and most western economies in the OECD would be in decline, were it not for migration.
