Are these correlated? My impression is that high-paying jobs tend to be low-physical-injury....
(Also, there are no shortage of barriers against women participating in high-mortality jobs - take the rules against women in combat for a particularly obvious example.)
Just intuitively, longer working hours (which may correlate with higher pay) and later average retirement age (which may correlate with higher paid jobs, especially with less physical demands), may contribute to greater probability of death from non-work causes, including age-related causes, happening while at work.
Yeah. For one small-scale example, the pay differential between the pizza delivery drivers and the in-store workers who make the pizzas. Roughly equivalent difficulty, drivers make $10-$15 an hour more due to tips and the risk of getting involved in a car accident or robbery. IIRC the gender ratio is more skewed towards men for delivery drivers than for in-store food service workers.
I suspect that white-collar senior management jobs contribute a lot more than pizza delivery jobs to the fact that men make more money than women in total. (But probably this is also true for median or first-decile wage?)
