[quote=barnaby33]develj I’d amend your formula as such: Productive Population Growth + Productivity Growth. Ethiopia had a population explosion in the 80’s, but it wasn’t productive. In fact it dragged Ethiopia down, (as does much of Africa’s population) relative to each countries economic capacity.

That’s a good point. For a large industrial country, GDP growth will be Population Growth + Productivity Growth (over the long term). Also, Global GDP growth will follow the formula as well. But, yes, you’re right in that certain smaller really chaotic undeveloped countries will not follow the formula – as it needs to be adjusted for the chaos.
