the demographic origins of poverty and statelessness

A very low population density may be at the heart of Africa’s historical under-performance when it comes to territorial state-formation and economic development. Bad geography, the very high disease burden and mediocre leadership, among other variables, may be but secondary causal explanations for Africa’s underdevelopment. The proximate cause may be how these secondary variables have affected and/or interacted with population density.

OK. That was a weak argument, but check this out.
