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.
