The Map
The archive, on the map
Every institution in the archive, plotted at its main campus: 886 colleges and universities across 55 states and territories, carrying 7,440 documented cases between them. Each dot links to that institution’s page.
Dots sit at an institution’s main campus, not at incident locations, and are sized by how many documented cases the archive holds. A bigger dot means a better-documented alerting history, often a sign of a well-preserved public alert archive; it is never a measure of how dangerous a campus is.

The archive also documents alerts at US institutions’ campuses outside the fifty states and territories. A US projection can’t hold them, so they are listed here rather than silently dropped.
How this map is made
Coordinates come from the archive’s institution gazetteer: main-campus points joined from the US Department of Education’s IPEDS directory where an unambiguous match exists, and hand-sourced from Wikipedia or OpenStreetMap where it doesn’t; every entry carries its source. The base map is drawn from US Census Bureau cartographic boundaries and rendered as a static image at build time: no tile servers, no third-party requests, nothing tracking where you pan. See the methodology for how cases themselves are documented.
