“You’re saying we don’t have the data to know what the usual death rate is for people who are 20,30,40,50,60 years old?”
Are all doctors in Canada one of those ages? No, they come in all sorts of ages just like people of other professions.
What we have is a death statistic for ONE single year for ONE specific group of people, doctors in Canada. We do not know if that statistic is representative of the average rate of deaths for that group, or higher than average, or lower than average. Thus it is a virtually useless statistic for making a comparison to try to determine anything about the current year’s rate compared to the AVERAGE rate, since we have no average rate at all.
