Agricultural potential may predict population density, which in turn could predict political centralization in the world sample, but not in the African sample.


First stage regression resulted in a positive, significant relationship between agricultural potential and population density in both the full sample and Africa subsample. The second stage regression resulted in a positive and significant correlation between population density and the full sample, but not with the Africa subsample.
