What are the 3 factors that induced rapid population growth?

This article comes from a response to a Quora question and sumarises a lot of material from my books on population theory.[1] It raises a number of factors that 'traditional' demographic theory usually cannot investigate due to its very narrow range of inquiry. There are more than three factors mentioned here and they are: Sea-level rise after last glacial maximus pushed populations together and created more fertility opportunities; Changing transport technology created more fertility opportunities; The rise of cities created more fertility opportunities; and the commodification of land and the rise of money created more fertility opportunities; local tribes had immunity to local pathogens so had lower infant mortality and better life expectancy; Inheritance law variations and the creation of land-less labor; The importance of fossil fuel (coal, petroleum) in expanding and supporting bigger populations; to which I could have added, the importance of wood supply as a pre-fossil-fuel limiter of population. I also mention that the theory explored does not conflict with Hamilton's inclusive fitness theory which Dawkins used to develop his 'Selfish Gene' theory, however it does identify countervailing forces to the associated 'Every creature breeds to the maximum' theory.
