Data Dump Saturday: United States Earnings by Education and Sex, 2015

In today’s data dump, there are three observations to keep in mind while sifting through the data. First, Graph 1 through Graph 4 illustrate that as education increases, earnings increase. This is the case for both men and women. Mathematically these observations are confirmed by a positive slope.

Graph 1

Second, there is an obvious earnings discrepancy between men and women at each level of the education ladder. As an example, the earnings of “Some College or associate’s degree” for men, $41,407, is slightly lower than the earnings of a “Bachelor’s degree” for women, $41,763. This is a fascinating statistic.

It should be noted that the purpose of this data dump is to provide information; the purpose of this data dump is not to take a side on earnings differences between men and women, nor is it to examine why it is so.

With that said, it should be noted that these discrepancies will change, increase or decrease, at different levels of the Super-system, which is the United States. For example, earnings differences between men and women will vary at the regional, the state level, the county, level, the city level, the zip code level, and so and so forth. And these earnings differences will change depending on geography, education (obviously), and industry and type of job, just to name a few parameters.

Lastly, Graph 2, Graph 3, and Graph 4 are simply partitions of Graph 1. That is, the three following graphs have been created to help the reader parse out the data a bit more clearly, i.e., make the data less busy. And it provides the reader with the opportunity to see the earnings behavior of the United States from different perspectives, while also providing the capability of comparing data in Graph 1.

Here’s Saturday’s data dump on 2015 earnings by education and sex in the United States.

Educational Attainment Data: Comparing Minnesota and the United States

We can use U.S. Census Bureau data to compare the educational attainment of the United States to any of the 50 states; we can use U.S Census Bureau data to compare the educational attainment of the United States to any city contained within the United States (provided data exists);  and we can use U.S. Census Bureau data to compare the educational attainment to compare states to each other, counties to each other, cities to each other, or any combination our hearts desire.

For this blog, we will compare the educational attainment of Minnesota, and the United States. In future blogs, we will compare other city, state, and country combinations. We will also compare city, state, and county; and we will even compare zip codes to one another. Which ones will explore? We will answer this question in due time.  Let’s begin.

United States

The United States is the Super-system. This means all 50 states and their respective counties, cities, town, zip codes, etc. are contained within the borders of the United States. Readers of this blog are familiar with this idea (for a more in-depth exploration of systems and sub-systems click here). This also means the United States meets the (3) systems’ axioms:

  1. A system consists of a set of elements.
  2. Elements in a system interact.
  3. A system has a function, or purpose.

We will take this axioms to be a given for this blog. Instead we will focus on the data. As we can see, the United States is second in every category except graduate and professional.

 

As the data illustrates, the United States has a lower median annual earnings (MAE) than that of Minnesota. This is good news for many residents of Minnesota who exceed the median annual earnings at each level of the ladder.

Minnesota

As readers of this blog will know, Minnesota is a sub-system of the United States. This means Minnesota meets the  (3) systems’ axioms:

  1. A system consists of a set of elements.
  2. Elements in a system interact.
  3. A system has a function, or purpose.

Again, and for our purposes here, this will be given knowledge to us realize we are dealing with different systems and should treat each data set as its own entity. However, we will observe that the three data sets in this blog have similar behaviors. That is, earnings increase at each level of the educational ladder. However, we observe there are subtle differences.

According to the data, Minnesota has the highest median annual earnings (MAE) at each level of the ladder. For example, the MAE for Minnesota is $51,239 whereas the MAE is $50,595 for the United States. It should be noted that at the professional and graduate level MAE for Minnesota is the same as the United States.

One final thought, it should be noted that the U.S. Census Bureau decomposes its data into regions and divisions as well. So, for example, Minnesota educational attainment data can be compared to Iowa educational attainment data and/or Wisconsin educational attainment data. And this is really just the start of what could be an exhaustive exploration of the educational attainment data. One could even compare men and women at each level of the United States system, if the data exists.
