There is no single statutory security ratio for events in the US. Operators start from a baseline near 1 security per 100 attendees and slide it by risk profile: alcohol service, standing crowds, multi-stage sites, and rival-crowd dynamics push it tighter; seated, credentialed corporate rooms relax it. Doors and bars get their own coverage on top, because those are the pinch points where incidents start.
Medical staffing steps through tiers rather than a straight line: a first-aid point for small rooms, a staffed post with an ambulance on standby in the low thousands, and a physician-led field medical unit at festival scale. Your medical provider and the AHJ set the real numbers from the event medical plan; this tool tells you which conversation you are about to have.
