Calls Affected Per Year
—
calls annually with location data issues
Additional Response Time Per Year
—
minutes of delay from location uncertainty (2.4 min avg per affected call; NENA)
EMS Cost of Delayed Response
—
in EMS unit time attributed to location data delays annually
Cardiac Arrest Risk Window
—
affected calls per year. Each additional minute of EMS delay reduces cardiac arrest survival probability by ~10% (American Heart Association).
School Safety Note

First responders entering a school without accurate indoor maps spend an average of 3–5 additional minutes locating rooms during an active incident. For a jurisdiction with K–12 facilities, indoor mapping gaps compound location data risk significantly beyond what standard address-level accuracy can mitigate.
