Age Structure Models of Largest Cities in the South of Russia

This article examines age structure models of largest cities in the South of Russia. The research studies the parameters of the age structure of population, the factors contributing to the growth of demographic load and the disproportion of age structure of the population of largest cities in the South of Russia. The study used a statistical method, including the collection, processing, analysis of demographic statistics on the age structure in the considered cities, the calculation of demographic coefficients, their examination and interpretation of the obtained values. The research is based on the hypothesis of accelerated population ageing in the largest cities that demonstrated an increase in the share of the population over the working age along with a decrease in the share of people under the working age. It was concluded that all large cities in the considered region are characterised by a model of regressive age structure of population; a more positive situation is observed in cities with a higher birth rate.
