This study examines the effect of intercity transportation and communications infrastructure on urban concentration on a sample of 84 countries between the years 1960 and 2010. By comparing the effects of interregional transportation and communications infrastructure on primacy and urbanization, I find that (1) such investments promote population dispersion amongst connected areas and (2) population concentration from unconnected locations into connected ones. Therefore, intercity transportation and communications infrastructure is only effective at reducing excessive concentration when the dispersion effect exceeds the concentration effect.
