APS Enrollment Data

Much of our work in Research and Evaluation involves looking at student outcomes, as demonstrated by the earlier blog posts about Milestones. But we've had several requests for enrollment information lately, so we pulled the October student count data from GADOE and made the following visual:

Mouse-over the visual to get exact numbers. The graph shows that the number of total students in APS has decreased from 59,560 to 51,500 students from 1994 to 2015. But there has been some increase since the 2009 low of 48,909. Demographics have also shifted: from 91% black in 1994, to 75% black in 2015.

The graph has several interactive features: choose a specific school or grade using the filters on the right, or use the tabs at the top to change visuals. The images below show a few different views that can be made using this visual.

The top graph was made by filtering to Lin Elementary School. The next graph was made by selecting the "Over-Time Multi-Select" and selecting all KIPP schools. To make the final graph, select the "Enrollment by Grade" tab and change the graph type to "Line".

Some schools in the state data file that were closed at least ten years ago do not have school names. The data for these schools appear if school name "Null" is selected.

The three graphs above are screenshots, but Tableau Public also allows users share a link to a customized graph. After selecting filters, click the "share" button in the bottom right and then copy the link. Did you make any interesting graphs with this tool? Or have questions?
