Simply the proportionate ratio of deaths in group III to the total number of deaths in all type groups (in other Words the deaths from all causes) in the age interval 50-54. Such ratios are usually known as proportional death ratios. It is readily seen that these proportionate death ratios are dependent on the deaths alone and absolutely independent of the number exposed to risk, provided tne total number of deaths from all causes in a ...certain age group is large enough to eliminate variations due to random sampling. 1 In other words, we can find 1 Strictly speaking this statement is only true for an age interval of one year or less and may in the case of large perturbing influences in the population exposed to- risk be subject to appreciable errors when we use large age intervals of 10 or more in our grouping for the com- puting of R{x). When the age interval for the grouping of causes of deaths by attained ages is 5 years or less the error committed in assuming R(x) as being indepen- 128 Human Death Curves.
