This map is based on an analysis done by my coworker Meg Wall for the Sustainable Communities Index. At its core it is a point density analysis of the quality and quantity of elementary school slots within one mile of any given point in San Francisco. Rather than using a regular grid, Meg used the San Francisco street grid to calculate the point density around each intersection, then weighted that value by distance, Base Academic Performance Index (API), and enrollment numbers. The results show that residents of Western San Francisco have significantly better access to elementary schools than the residents of Eastern San Francisco.
Zoom in on your neighborhood... or hover over the elementary schools (black dots) to see enrollment numbers, APIs, and whether or not the school has a garden.
