Genetic demographic study of shors in Tashtagolskii raion of Kemerovo oblast: Population dynamics and changes in the sex and age composition

Genetic demographic study of shors in Tashtagolskii raion of Kemerovo oblast: Population dynamics... The population dynamics and changes in the sex and age structure of the Shor populations of four rural district municipalities of Tashtagolskii raion of Kemerovo oblast (Kyzyl-Shorskii, Ust-Anzasskii, Ust-Kolzasskii, and Ust-Kabyrzinsskii) with time have been analyzed. The Shor populations have been found to have contained a high proportion of people under 18 years of age during two periods, 1940–1955 and 1970–1975 (38.12–46.38 and 40.98–54.97%, respectively). However, the population reproduction pattern changed into the “reduced” one in all the municipalities studied by the early 2000s. Although there are some regional variations, a common trend towards rural population aging has formed: the man age in the Tashtagolskii raion population has increased by 7.52 and 6.94 years for men and women, respectively, during two generations; the natural sex ratio has been disturbed in both the prereproductive and reproductive populations. The total population size and effective reproductive size have decreased in three out of the four rural subpopulations studied. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Genetics Springer Journals

Abstract

The population dynamics and changes in the sex and age structure of the Shor populations of four rural district municipalities of Tashtagolskii raion of Kemerovo oblast (Kyzyl-Shorskii, Ust-Anzasskii, Ust-Kolzasskii, and Ust-Kabyrzinsskii) with time have been analyzed. The Shor populations have been found to have contained a high proportion of people under 18 years of age during two periods, 1940–1955 and 1970–1975 (38.12–46.38 and 40.98–54.97%, respectively). However, the population reproduction pattern changed into the “reduced” one in all the municipalities studied by the early 2000s. Although there are some regional variations, a common trend towards rural population aging has formed: the man age in the Tashtagolskii raion population has increased by 7.52 and 6.94 years for men and women, respectively, during two generations; the natural sex ratio has been disturbed in both the prereproductive and reproductive populations. The total population size and effective reproductive size have decreased in three out of the four rural subpopulations studied.
