In a post last week I compared the allocation of economic activity in North Dakota with the United States. North Dakota has a larger share of activity in agriculture and extractive industries, but less in industries like information. There are many factors that influence the share of economic activity including resource endowments, transportation networks, and the list goes on. Consequently you need to be careful drawing policy conclusions from differences in allocations between two geographies. It could be very easily explained by resource endowments, such as oil in the ground.
