Methodical approaches to evaluating the expected life of a population

The paper studies the impact of medical and demographic indicators on the life expectancy of the population of the Voronezh region. Using the STATISTICA 10 program, the influence of various factors on this indicator has been established, including mortality, fertility, per capita incomes, the number of medical personnel, the number of hospital beds and the correlation between them. Diagrams of dispersion and graphs of 3M surfaces were constructed for the dependence of the life expectancy of the population of the Voronezh region on the factors under study.
