Dataset Request: Arlington County Planning Units

Arlington County provides a map of all the planning units here:
http://www.arcgis.com/home/item.html?id=5dc0da42e03a4c7192826e3b8ef91810 and https://www.apsva.us/wp-content/uploads/2014/07/PlanningUnits-2017-Map.pdf

This data is used to create school attendance zones, as shown here:

Ideally, the data included in this set would be exportable as the standard CSV/XML/JSON, and a single row/object would include at least the following information:
Planning Unit ID
Student Population (Elementary School)
Student Population (Middle School)
Student Population (High School)

As Arlington Public Schools (APS) are working through the school re-zoning process, having access to the raw data for planning unit boundaries would allow for optimization models to be developed and for results to be shared with APS for consideration in their final boundary change decisions. As part of the boundary file dataset, it would also be beneficial if the dataset included student population to be factored into the optimization model.

Arlington Public Schools is consulting internally about the level of effort required to provide student information at the Planning Unit level on the County’s GIS portal and satisfying privacy concerns related to making such student information public. In the meantime, please reference the APS statistics page for information on student demographics. At this time we cannot publish the enrollment information but will leave this request open until there is a determination on APS's ability to share student data at the Planning Unit level on the County’s GIS portal.
