RESEARCH METHODS
Data on town-SAU organization and school choice options were collected from public sources, either through the Maine Department of Education website, municipal websites, or through conversations with school district or municipal officials. The full data set and sources, where applicable, can be found on a public spreadsheet.
To develop the accompanying map visualization, data from the State of Maine Geographic Information System (GIS) for municipal boundary shapes were matched to school choice data of corresponding municipalities and unorganized territories.
