59 Before leaving this comparison of the Province with the miners, it should be shown that.their age distributions are reasonably the same. That this is the case can be observed from the following tabulation: Age Distribution of Adult Males for the Province of Quebec, 1951 (Rapport, 1954) Age Group 20-44 45-54 55-64 6$ * Total Number 727,135 188,952 128,944 113.467 1, 158,498 Percentage 63 16 11 10 100 Percentage Combined Cohorts 66 19 10 5 100 It should be remembered that the miners retire and con sequently, it can be expected that the oldest age group will be larger in the general population. The data presented in Table 23 indicates that the lung cancer rate generally decreases after age 70, and we could expect the rate for all people over 65 would be smaller than the rate for a group of 65 to 75, which would apply to the oldest group of mincra. It is felt that by using the whole adult male population, we have developed rates which are somewhat lower than if we had been able to exclude the general population over 75.
