So an ongoing project that is taking a significant amount of my time (and thus taking time away from blogging) is executing a full population projection for North Dakota for the next 50 years. There seem to be some special issues when looking at the state level, for a small population state.

As part of my construction of a population projection for North Dakota my reading and data analysis focused significantly on demographic data and trends in North Dakota. One of my concerns with trends in North Dakota is that with a low population base even moderate flows will lead to rate changes and possible adjustments in trends. The other issue for North Dakota is that the proximity to a larger neighbor in Minnesota can somewhat complicate the analysis. For example, this graph.

I am teaching demographic methods, population analysis, whatever you want to call it this summer. The class title is not the really important thing to me, it is more a matter of content. Don’t get me wrong, I am all for accurate titles, but neither title is deceptive and most people have no idea what it is anyway regardless of the title.
With that in mind I thought I would include a few maps from my recent presentation at the state demographics conference. I gave the morning keynote address and talked about the basics of some of the demographic changes as well as the implications of those changes. The following series of maps is pretty important confirmation of what happened in North Dakota.
It will be really important to pay attention to the color scale on these maps. The lighter the color the higher the amount of net migration per 1,000 people in the population. Net migration is the amount of inflow less the amount of outflow, so higher numbers imply a higher local population, at least due to the migration aspects.
Clearly we see the impacts of the oil boom here. Enormously positive net migration into western North Dakota, particularly the Bakken region was the norm in 2011 and 2012.
For those interested in a little more detail here is a nice little graph for you:

A recent report out by the Center on Budget and Policy Priorities (available as a pdf here) looks at the connection between state tax rates and migration between states. Or maybe it does not. They find little connection between changes in state tax rates and the migration between states.
