Deaths that wouldn't have occurred had a mass evacuation not taken place.
Here's a paper analyzing the evacuation-related deaths from Hurricane Rita.
> A majority of the deaths (90/108 or 83.3%) were related to the mass evacuation process. Of these deaths, 10% were directly related to hyperthermia in motor vehicles. The combination of traffic gridlock and high temperatures, limitation of air conditioning to reduce fuel consumption, reduction of oral intake to decrease restroom visits, and conservation of limited supplies is suspected.
