Here's what I'd be curious to discover...
Now, obviously, the "population" in the entire Walt Disney World area will ebb and flow depending on time of year and day of the week. But if you took an average estimate of the population of WDW--and by that I mean anyone who's on the property, day guests, resort guests and all employees--and compare it to a location anywhere else in America with a comparable population, where would the mortality rate be greater?
As has been previously stated, the recent unfortunate deaths at WDW that have grabbed headlines were based on unknown pre-existing conditions exacerbated (sp?) by the attraction (and possibly other factors, like the heat, or stress from the crowd levels, lack of sleep due to excitement, etc.). Meanwhile, people die from situations that aggravate pre-existing conditions every day. A sudden scare could effect anyone with an unknown heart condition. Not to mention any natural causes of death. So, when people like to act as if WDW is spuh-ooooky because of these unfortunate incidents, it might serve them to know how many deaths might occur in similarly populated areas across the country.
