about 20 years (a decrease in the male population
shall be observed from the age of 50-54).
An important factor in maintaining the stability of
the demographic environment (situation) is the
comfortable living conditions of a person in a
particular area of the city and region.
However, "comfort" is a collective, complex
concept determined by the ratio of at least four
particular exogenous factors: a) the level of
anthropogenic transformation of the air environment;
b) the state of the water management complex; c) the
state of the soil cover; d) the social and medical
situation in a particular area. Note that in some cases
all four factors are interrelated and can lead to the
effect of cumulation of negative effects on human
health and life expectancy.
The analysis of the listed particular exogenous
factors made it possible to identify comfortable and
hypocomfortable areas of the Volgograd region,
including the city of Volgograd. The latter in the city
include Kirovsky, Krasnoarmeisky,
Traktorozavodsky districts, in the region -
Gorodishchensky, Mikhailovsky, Novoanninsky
districts. Later, using the method of “copies of pairs”,
the relative comfort of a number of rural districts was
established - Kalachevsky, Uryupinsky, Frolovsky.
However, the analysis of long-term temporal
trends of the demographic situation requires the
search for rational quantitative indicators that clearly
reflect the ratio of the male and female population in
comfortable and hypocomfortable areas.
In connection with the above, in these studies,
along with an assessment of the general demographic
situation in comfortable and hypocomfortable areas
of the Volgograd region, the analysis of the dynamics
of the effective indicator, which clearly characterizes
the ratio of the number of men and women in the
population under consideration: the gender
differentiation coefficient (GDC), was carried out.
The study of the GDC trend in 13 age groups
(from "16-17 years old" to "over 70 years old") was
carried out differentially in different districts of the
Volgograd region, taking into account the comfort or
hypocomfort of living there. The Volgograd is
represented as a whole, due to the difficulty of
obtaining reliable statistical data on the gender
structure of the population of different age groups in
the inner city areas. Nevertheless, it should be noted
that the trend towards a decrease in the male
population, established in the present studies,
continues for several decades. Based on the data
obtained, a significant decrease in the influence (loss
of dominance) of the “comfort / hypocomfort” factor
for the formation of GDC in the older age groups of
the population was established.
After fifty years, upon reaching the pre-retirement
and retirement age, emotional-psychological,
inherently endogenous factors, the transformation of
a person's social status, a deficit of full-fledged, active
leisure become predominant in terms of limiting life
expectancy and determine the rate of premature aging
of the male population of the Volgograd region.
In view of the above, further in-depth studies are
needed to analyze the endogenous factors of aging.
Undoubtedly, the results of such studies will make it
possible to highly effectively influence the
prolongation of active longevity and an increase in
the life expectancy of the population of the Volgograd
region.
