A NOVA SCOTIA LIFE TABLE A. C. JOST 67 



The calculated death rates of the individual ages for both 

 males and females, from which the "probability of living" was 

 obtained, are shown on the accompanying chart. It will be 

 seen that a fair degree of "smoothness" was secured. In the 

 table itself will be found, not only the expectation of life (the 

 curtate expectation) for the period given, but for the purpose 

 of comparison the corresponding expectation obtained from a 

 life table of the Province based upon figures of the two years 

 1910 and 1911. 



The difference between the "curtate"and the "complete" 

 expectations of life should be noted. These for practically all 

 ages except those of the extremes of life, differ from each other 

 by one half year exactly — the curtate being the shorter. 



Many published tables give "complete" not "curtate" 

 expectations, and, if comparisons are being made, this fact, and a 

 possible difference in nomenclature, must be kept in mind. 



In addition, reference should be made to another term, 

 frequently used, namely the "Probable duration of Life." 

 This is to the age at which half the life table population 

 shall have ceased to exist, or in this case, when the 

 100,000 persons with whom life table started have become 

 50,000. This point will be found to be between the ages 

 of 62 and 63 in the case of the males — and of 64 and 65 

 in the case of the females of the Provincial population. Its 

 position has changed relatively little in the period between the 

 two censuses.
