It is a widely held belief that Star Trek redshirts have a higher death rate compared to those who wear uniforms in other colors. Matthew Barsalou from statistic-centric magazine Significance looked into this widespread presumption and came up with some pretty surprising results.
Barsalou used casualty figures compiled on Star Trek wiki Memory Alpha and came to the conclusion that those in redshirts aren’t in such a perilous position after all:
Although Enterprise crew members in redshirts suffer many more casualties than crew members in other uniforms, they suffer fewer casualties than crew members in gold uniforms when the entire population size is considered. Only 10% of the entire redshirt population was lost during the three year run of Star Trek. This is less than the 13.4% of goldshirts, but more than the 5.1% of blueshirts. What is truly hazardous is not wearing a redshirt, but being a member of the security department. The red-shirted members of security were only 20.9% of the entire crew, but there is a 72.2% chance that the next casualty is in a redshirt and 64.5% chance this red-shirted victim is a member of the security department.
So, it appears that being a member of the security department is the real killer here. Regardless, I think that the group surrounding Benedict Cumberbatch in Star Trek: Into Darkness is doomed.
