North Dakota’s economic performance and success is not news anymore. Well, alright, its news, but most people know about it. I have given interviews to media outlets around the country and the world about it, as have many others. So it is not a secret. So if there was an economic motive to migration, and there often is, people already know about it. Here is a graph of ND population change, migration in, and migration out. I calculate migration out as the difference between migration in and total population change.
