On the study of the experience of the adult Tatar population

Determining the survival rate of the population and the order of its extinction is one of the main tasks of social and hygienic examination, the sanitary characteristics of a particular region of a particular population group. Without these data, it is difficult to get a correct idea of ​​the sanitary state of the study area. On the other hand, the study of the problem of experiencing is a rather difficult task and requires the use of complex methods. The essence of the method is to compare the numbers of the distribution by age of the deceased with the numbers of the distribution by age of the living and to obtain the probability of survival to the next age period. The probability of survival obtained in this way makes it possible to calculate the order of extinction of a non-existent (hypothetical) generation with age-related mortality equal to the force of mortality for the period of time for which the census took place.
