For instance, if 5% of people in category A leave each year, and 30% of people in category B leave each year, and 10% of each of them cite sexual harassment as the reason to leave, I would say that we have a much bigger problem with sexual harassment against category B. (And, at the same time, I would also say that anyone saying that category A doesn't face this problem at all / it's not worth addressing / whatever is wrong!)
