Arlington Analytics developed the Arlington Model, which keeps track of every single property in the county. We match that data with data from the U.S. Census, Arlington Public Schools, Virginia State Police, various maps, development reports, a large number of historical reports and studies, and other data to create a comprehensive database on Arlington county. We use this data to determine how each type of property contributes to school enrollment and population growth, which in turn affects the budget. The full version of the Arlington Model has numerous options that do not present well on the web. Nonetheless, we present a set of apps that provide most of the functionality of the full version, and offers all of the same major insights that the full model provides.
Student growth is the most important component of spending growth going forward. Nonetheless, a more granular look at where students are going to live will help plan for the location for additional schools as well as the need for other investments such as buses. Arlington Analytics has components that forecast students at a planning unit level. We have the ability to forecast the number of students per school based on development and student growth by type of property. In addition, by merging this data with school walk zones, we can forecast the need for transportation resources.
