Maret School: Exploring Inequality through GIS

Using GIS to map inequality is a powerful tool for understanding how inequity and place are inherently connected. Recently, the Maret School and Blue Raster partnered to give students the skills and resources necessary to map historical inequality in DC to deliver valuable resources for the DC community and beyond.

Blue Raster developed and delivered basic and intermediate GIS instruction for Maret’s Mapping Inequality in DC class.

Using Blue Raster’s instructions through ArcMap and ArcGIS Online, students learned to:

  • Create, style and update maps.
  • Add Census demographic layers and features to maps.
  • Visually analyze historical patterns in data.
  • Create compelling static maps, as well as interactive Story Maps to illustrate and explore inequality.

Students explored issues such as redlining, health systems, access to public transportation, and other issues relating to inequality.

Students worked in teams to create research questions and then blend demographic data with a digital mapping
program to draw conclusions about patterns of inequity in DC. Students learned to take advantage of available resources, including open data and census portals, in order to produce insightful analysis.

Examples of open data sources that are available to students.
Blue Raster understands that equity and place are inherently connected. We believe that every aspect of a class – researching, learning, analyzing, and communicating – benefits from ArcGIS and spatial thinking.

Education Data Leaves the Classroom with EDGE Geodata

Geography plays a vital role in our schools: both inside and outside the classroom. The new release of the Education Demographic and Geographic Estimates (EDGE) Geodata site gives the public access to authoritative, up-to-date geographic education data for the entire U.S. Using this data effectively helps to answer some of the most difficult questions that face our school systems today: How far are high schools to the nearest community college? How many low-income households are contained within a school district? How do students in rural schools compare in math and science to urban schools?

Blue Raster and the National Center for Education Statistics (NCES) EDGE Program believe that releasing this spatial data in an open, easy to use format is essential in making data-driven decisions on school funding, student poverty, and teacher supply and more.

The EDGE Geodata site contains a variety of data sorted into four Data Categories:

  1. K-12 Schools
    Survey data from the Common Core of Data (CCD) for over 100,000 schools across the United States and over 18,000 School District Office Locations updated annually, as well as School Attendance Boundaries for every elementary, middle, and high school across the United States collected bi-annually.
  2. Postsecondary Schools
    Over 7,000 Postsecondary School Locations across the United States collected by the Integrated Postsecondary Education Data System (IPEDS) annually. This dataset includes Certification, Associate’s, Bachelor’s and Graduate programs.
  3. School Districts
    Developed by NCES EDGE Program, School District Boundary Composite files to provide public education for residents, released annually.
  4. Locale Boundaries
    Developed by NCES EDGE Program, a geographic locale framework that classifies all U.S. territory into twelve vategories ranging from Large Cities to Remote Rural areas.

Each dataset can be downloaded as full dataset, or filtered and then downloaded as a Spreadsheet, KML, or Shapefile, for use in GIS and non-GIS formats. Within the ArcGIS Open Data Platform, each dataset is available for further data drill-down in the API Explorer. Users can create custom Queries within the fields or apply spatial filters, and get outputs in JSON format.

All data items are hosted in the robust, cloud-based ArcGIS Online platform, and hosted in a custom configured Open Data site.
