A casualty is an individual who has suffered death or injury as a result of a crash.
It is not at all uncommon for a single crash to result in more than one casualty. Because of this, the total numbers of crashes and casualties cannot be expected to be the same. When reporting statistics, great care should be taken to distinguish between numbers of incidents which occurred (crashes) and the number of people injured as a result (casualties).
STATS19 records certain key features of all casualties associated with each crash, including:
- The severity of the injury
- Personal details about the casualty, including sex and age
- How the casualty came to be involved in the crash, including
- Which vehicle accounted for the casualty's involvement
- What the casualty had to do with that vehicle (known as the casualty class)
Casualties in MAST
Socio-demographic information about casualties
Postcodes of casualties are also recorded by STATS19. This makes it possible to analyse the socio-demographic profiles of communities in which casualties reside. MAST uses casualty postcodes to link to the Mosaic profiling system, and enable insight into the provenance of groups who are most at risk of involvement in crashes.
