A method for predicting a survival rate among individuals, where the survival rate depends in part on a responsiveness of emergency personnel, and the responsiveness of the emergency personnel depends in part on an amount of time taken to route an emergency call to a primary emergency response center, includes determining, by a computer system, a number of emergency calls initially routed to a primary emergency response center. The computer system determines a number of emergency calls initially routed to a secondary emergency response center that, in turn, routes the emergency calls to the primary emergency response center. The computer system calculates a survival rate amount individuals according to a function of the determined number of the number of emergency calls initially routed to a primary emergency response center and the number of emergency calls initially routed to a secondary emergency response center. The calculated survival rate is displayed on a terminal.
