For those that question the impact of the oil boom, I offer up this post on birth rates. Now the answers are not quite as obvious as you might expect. It is probably important that you recall my earlier post about the net migration by county for North Dakota (found here). The beginning year for our look at birth rates is 2011 where we see the leaders in birth rates are counties with sizable Native American populations. There is, as yet, no boom in the Bakken area, and there is a remarkable degree of consistency as far as rates across the state.
