Since I was able to get the sunburst chart to finally work properly. I decided to take a look at the data I entered. For some reason, the enrollment for winter 2021 is really low (COVID and short term?), so I decided to pull numbers of a more typical term (still COVID) to get a better idea of actual enrollment. I wrote the code in a text file, so I have not yet taken a look at the chart. However, I know from just looking at the data that Prince George’s County has the highest headcount enrollment. This is logical because Bowie State University is located in Prince George’s County.

Getting the COde to Render Locally

In my last post, I said that I could not get the Sunburst Chart to render properly out of CodePen. I walked away with plans to go to bed. Getting ready for bed I did a few minutes of googling and found a Reddit post from three years ago that explained my issue. Apparently, since it was running locally I need to add “https:” prior to the resources in the HTML part of the code.

Below I have quoted partly how it was explained on the Reddit post. Basically, without the https:, which is sometimes assumed and can be assumed when it is running off CodePen, the computer does not know what it looking at. Thus, my code will not render. Since I am new to this and kind of just trying to make things work, I will be adding in the “https:”

…when you don’t use an explicit scheme, then your brower will use the scheme of your page. … This is also why this gave you problems when running locally: if your page is served under file:///some/path/to/your/file.htlm then the url// mascdn.bootstraphcdn.com/font-awesome/4/2.0/css/font-awesome.min.css resolves to file://maxcdn.bootstrapcdn.com/fount-awesome/4.2.0/css/font-awesome.min.css, which doesn’t exist. …

When I was running the code without the “https:”, it would just spin its wheels. There was no error code.

Thoughts about SunBurst Chart

I need to type in all my data before I can decide if I like a chart. The Sunburst chart is kind of interesting, it allows for drilling down of data, which I really like. The issue with the particular chart is that there is so much data the chart is kind of difficult to read. In my first version, I did not have the in-State enrollment divided by region and it was even harder to read.

Again I have run into the issue of not being able to get an Amcharts graphic to render on my site. I can make it render in CodePen, but when I export the “pen” it will not render locally. I also can not get it to render using the WordPress plugin for Amcharts. So I am going to park this here until I can figure out why I can not get it to render.

In my previous post, I built my first treemap using Amcharts. Today I built another treemap, this one is 3 levels deep. I am unsure about the presentation of the data in this manner, it may not actually be very useful. However, since I was able to successfully explore building a multi-level treemap using the Amcharts demo I will call it a success.

In this example, I was able to get the level 1 labels to appear, which I was not able to figure out yesterday.

Today I am testing out a treemap that I made in Amcharts. I made a treemap of the students that transfer into the University System of Maryland in 2020. The top layer is the education sector, the second layer is the institution. I am still having a bit of trouble getting it to behave as I would like. I would like the second layer names to appear in the boxes, but I can not seem to get it to work as it does in CodePen. Again I got it to work in CodePen using an Amcharts demo as a model, but again I ran into an internal 500 error when I tried to transfer the code over. So I rewrote the code keeping out the pieces that were not rendering properly.

The treemap clearly shows that there are a large number of transfer students from the US Armed Forces, in part because of the University of Maryland Global Campus. I may make another treemap that excludes transfer students from the University of Maryland Global Campus.

I figured out how to show the size of the institutions before drill down, but not the institution names. There is likely a simple way to show the labels on a treemap in Amcharts, but I have not yet figured out how. I think that I like the first style better, but I will need to test both versions.

UPDate

I realized while I was digging into the data further that I missed the 16,362 students that transferred from “other” out-of-state institutions and 5 students that transferred from “other” MICUA/MD private institutions. I missed them because the institution details is only provided for the top 15 institutions in each of the drill-down categories.

Today I am taking a look at the dual enrollment data published by the Maryland Longitudinal Data System (MLDS) Center.

According to the data, 85% of 12 graders in the 2018-2019 student year who earned dual enrollment credits between 9th and 12th grades (academic years 2015-2016 to 2018-2019) enrolled in college in fall 2019. Of those who enrolled in college: 36% enrolled in an in-State community college; 35% enrolled in an in-State (public or private) four-year college; and 28% enrolled in an out-of-state college. This is showed in the Sankey diagram below.

I wish I could match up the dual enrollment students with the general student population. It would be nice to see if the behavior of students that dually enrolled differs from the general student population. I will take a deeper look at the data in the future to see if I can use math to make any conclusions.

As of yet MLDS Center has not yet published the general college enrollment data for the 2018-2019 cohort year. However, typically, 50% or less of high school graduates immediately enroll in college. Thus, students that participate in dual enrollment programs (unsurprisingly) seem to enroll in college at a higher rate than students generally.

Source: Maryland Longitudinal Data System Center, dual enrollment courses and credits: 2018-2019

According to the data set, of the 6,237 students that enrolled in-State following participation in a dual enrollment program, 3,012 in-state students, or 48%, enrolled at the college of dual enrollment. A further 2,936 in-state students, 47%, participated in a dual enrollment program at a community college and enrolled at an in-state four-year institution.

notes about the Data

  • The data shows data on the college enrollment patterns for 2018-2019 12th grade high school students with dual enrllment activity at any point between 9th and 12th grade. The initial population was selected by identifying studetns who had noth a high school enrollment and a college enrollment recored in the 2018-2019 academic year (fall to spring). Summer enrollment information was excluded from this analysis.
  • This diagram is the result of me exploring the limits of the data and the graphing software. The numbers and math have not been checked.

Short answer. Yes, free-and-reduced price status likely impacts college segment of initial enrollment. See the pretty Sankey diagram below that shows the college segment of initial enrollment for high school graduates by free- and reduced-priced meal (FARMS) eligibility status. However, read my data notes below before making any conclusions.

Most notably 47% FARMS eligible high school graduates failed to enroll in any college segment compared to 24% of non-FARMS eligible high school graduates. Also, 10% of FARMS eligible high school graduates initially enrolled in an out-of-state college compared to 24% of non-FARMS eligible high school graduates.

Long answer. As an analyst, I can think of a long list of reasons why this data does not answer this question. The first being is that the data source does not list actual numbers, just percentages. So I had to back into the numbers I used in the diagram. However, due to rounding, the numbers do not add up to the proper totals. If this was for real analysis I would try to get the actual numbers. I need to use numbers, even if they are not quite correct to get the diagram to render properly.

But for this project, I am just attempting to see if I can code this type of diagram and getting a general sense of what the diagram would show. On that end, it is a success. I can do the coding, I am sincerely hoping that you can see the diagram above right now. I also think I really like the visual effect. I think it works well when you have a few categories for each node.

Notes about the Data

  • The number of students are estimates from the percentages published by the Maryland Longitdinal Data System Center. I have not fully checked my calculations, this is primarily for me to learn how to create the diagrams using the software. I am also attempting to learn which types of data visulizations I find useful and worth pursuing. I also am trying to better understand the data.
  • Due to rounding in the data source the numbers do not add up to the correct totals. This is just for a general idea of the data, not for specifics.
  • Some notes adapted from those provided by the Maryland Longitudinal Data System Center, all errors are my own.
  • The number number of years following high school graduation impacts the initial postsecondary enrollment numbers. Graduates who enrolled in Private Career Schools or Continuing Education and Training Certificate sequences are not included.
  • This dashboard uses “initial enrollment,” which counts only the first enrollment of a student after graduation. For example, a student graduates high school, enrolls in a summer community college course, and then enrolls in an out-of-state college in the fall. The initial enrollment count for that student is one in-state enrollment. Other methods of counting enrollment may count that student as one in-state and one out-of-state enrollment. Accordingly, when reviewing, and especially when comparing post-secondary enrollment reports, it is important to understand how the enrollments are being counted.
  • The number of high school graduates reported on this dashboard includes: (a) only the counts of 12th grade graduates; and (b) eliminates any duplicate graduation recordsSome numbers are rounded or estimated due to data suppresssion. For general illistrative purposes only.

College of Initial Enrollment

During the 2013-2014 academic year approximately 58,300 students graduated from a Maryland public high school. Of those graduates, approximately 39,900 students had enrolled in college by the following year. The data set captures the higher education segment (community college, public four-year, State-aid independent institution, or out-of-state institution) that a graduate initially enrolls.

As shown in the Sankey diagram, high school graduates enrolled initially as follows: 30% at community college; 17% at a public four-year institution; 3% at a State-aided independent institution; and 19% at an out-of-state institution. An additional 32% of high school graduates did not (yet) enroll in a postsecondary education captured in this dataset.

This data set only captures the college of initial enrollment. For example, if a student enrolls in a community college for a summer class and then enrolls in a public four-year institution in the fall, the student will be recorded as enrolling in community college.

I wonder how the college of initial enrollment for public high school graduates compares to the total enrollment of the various sectors.

Refining the Pipeline

I spent yesterday trying to figure out how to create a divergent stacked bar chart in amcharts that would display properly on my website, which is based in WordPress. I was unsuccessful. I will need to continue reading through the documentation which is written for people who actually know how to code. Since I got frustrated with my original project, I decided to return to the immediate college enrollees pipeline again to refine it as I learn more about how amcharts operate.

This version of the Sankey diagram is a bit more readable. I was able to wrap the label text and add more space on the right-hand side. I also added code that will allow the data or the image to be downloaded, which I think is a cool feature. I am still having a bit of an issue getting the amcharts diagrams to display as part of the blog, but they work when looking at an individual post. I also added int the percentage numbers, each of which had to be separately added. I have read in the documentation that it is possible to load data into an amcharts from an external source, such as a spreadsheet, but I have not yet figured it out.

As with other versions of this diagram, the biggest weakness is that it does not capture transfer students.

Immediate College Enrollees Pipeline

Overall 65% of students that enrolled in college directly after high school graduation graduated college, from the same sector, by age 25. An additional 3% of students were still enrolled in college (in the same sector). Looked at another way only 31% of high school graduates graduated from college from the same sector that they enrolled in.

Notes about the Data

  • These notes are adapted from the notes provided by the Maryland Longitudinal Data System. Any errors are my own.
  • To be counted as a community college graduate, the student must have enrolled in any community college and graduated from any community college. Students who start at a community college but graduate from a college in another sector are not counted as graduates. Students who start in another sector but graduate from a community college are also excluded. To be counted as persisting (still in college), the student must have NOT graduated from any community college and be enrolled in any community college in Fall 2019. Some students who enrolled in community college transferred from the college and are enrolled in another four-year public, state-aided independent, or out-of-state institutions. Those students are not reported here.
  • To be counted as a public-four year college graduate, the student must have enrolled in any four-year public and graduated from any four-year public. Students who start at a four-year public but graduate from a college in another sector are not counted as graduates. Students who start in another sector but graduate from a four-year public are also excluded. To be counted as persisting (still in college), the student must have NOT graduated from any four-year public and be enrolled in any four-year public in Fall 2019. Some students who enrolled in a four-year public transferred from the college and are enrolled in another community college, state-aided independent institutions, or out-of-state institutions. Those students are not reported here.
  • To be counted as a State-aided indepented college graduate, the student must have enrolled in any state-aided independent institutions and graduated from any state-aided independent institution. Students who start at a state-aided institution but graduate from a college in another sector are not counted as graduates. Students who start in another sector but graduate from a state-aided independent institution are also excluded. To be counted as persisting (still in college), the student must have NOT graduated from any state-aided independent institutions and be enrolled in any state-aided independent institutions in Fall 2019. Some students when enrolled in a state-aided independent institutions transferred from the college and are enrolled in another community college, public, or out-of-state institutions. Those students are not reported here.
  • The out-of-state table above evaluates within sector college graduation independent of college of enrollment. To be counted as a college graduate, the student must have enrolled in out-of-state institutions of any type and graduated from an out-of-state institution of any type. Students who start at an out-of-state institution but graduate from a college in Maryland are not counted as graduates. Students who start at a college in Maryland but graduate from an out-of-state institution are also excluded. Out-of-state institutions may be community colleges, public four-year, or other types of private institutions.

Public High School Graduates that Earn a College degree by Age 25

I am back at making Sankey diagrams to illustrate the pathway to college degrees. Today I have manipulated data published by the Maryland Longitudinal Data System Center. Look at the College and Workforce Outcomes for Maryland High School Graduates data dashboards and the college pipeline report. MLDS produces dashboards on three populations, immediate college enrollees, non-traditional college enrollees, and “complete” college enrollees. I used that information and a little fudging to make a Sankey diagram showing the pathway to a college degree, which for this data is defined as a postsecondary certificate, or an Associate’s, Bachelor’s, or Master’s degree or higher. Unfortunately, this data set does not track the type of degree earned or the pathway the students took to earn the degree, although I hope to play around with the data in the future making some educated guesses to illustrate those pathways. For this diagram, I used the class of 2011.

Approximately 78% of public high school graduates enrolled in college either full-time or part-time as degree-seeking or non-degree seeking at any point after high school graduation. Overall approximately 50% of students who enrolled in college at any time earned a college degree by age 25. Those who are reported as not earning a college degree by age 25 may be actively pursuing a college degree at age 25 or earn a college degree after age 25.

Notes on the Data

  • College enrollment and graduation from Maryland’s community colleges, four-year public institutions and state-aided independent institutions is evaluated using data from the Maryland Higher Education Commission. College enrollment and graduation from out-of-state colleges and in-state private colleges is evaluated using data from National Student Clearinghouse. National Student Clearinghouse reports college graduation for the five year period after high school graduation, which is approximately age 23. It is possible additional students graduate from out-of-state colleges or in-state private career colleges after five years. Those records are not available to include in this analysis.
  • Non-Traditional College Enrollment includes high school graduates that either delayed degree-seeking enrollment in college until age 20, or enrolled for the first time as part-time degree-seeking. Non-Traditional College Enrollment is not reported until two years have lapsed since high school graduation.
  • A high school graduate is considered enrolled in college if the graduate meets the definition of Immediate College Enrollment. Immediate college enrollment is defined as a high school graduate who enrolls in college as a full-time, degree-seeking student in the fall immediately following high school graduation.
  • Students reported as “No College Degree by Age 25” may be actively pursuing a college degree at age 25 or earn a college degree after age 25.
  • The data in the diagram has not yet been fully checked. This post is the product of an active learning process. I plan to revisit the data and diagram in the future.
