This paper analyzes the impact of information and communications technologies (ICT) on economic growth and agglomeration, emphasizing outcomes for regional inequality. ICT significantly displays the same features---increasing returns, knowledge spillovers---that drive both growth and agglomeration. However, in the data, cross-economy inequality has been rising for longer than has ICT been perceptibly influencing economic performance. In Europe, nation states show no special advantage in using ICT as a driver for economic growth; ICT clusters seamlessly transcend national borders.
