I was thinking about North Dakota and the population shifts and changes of the the last few years. The economics of the state are so clearly connected to the population changes, which are clearly connected to the economic changes in the state too. There really is an intense and important feedback relationship between population and economics in this state in particular.
I used the same data that I used for the map yesterday but plotted the ratio against median total earnings. Partly this was to see if there is a pattern to discern in North Dakota counties such as higher median earnings leading to an increasing or decreasing parity ratio. To assist in this examination, I added a linear regression line and a confidence interval and this is what I found.
Today is Equal Pay Day. If you go back to January 1, 2017 and move forward from there, a woman would need to work until today, April 10, 2018, to make what a man made by December 31, 2017. That is one form of comparison. I generated the following map from Census Bureau data for counties in North Dakota for median wage by sex.
The demographic transitions within North Dakota due to the Bakken oil boom are simply fascinating. These are part of my presentations at the North Dakota Demographics Conference. Some of this may be updated in the next few days because the Census Bureau released new data today that I am still working through even as I write this. Multitasking with writing blog posts and computer code is one of my skills. Ask JT about it on his radio show sometime.
So JT asked me about the existence of a labor shortage in Grand Forks. Essentially asking if there really is one or is it something we make up to explain some issue in local labor markets. Let’s first understand that this can change from time to time, month to month as it were. Let’s go to the data.
