[Genetic demographic structure of rural populations of Kyrgyzstan]

The genetic demographic parameters of rural populations of Kyrgyzstan have been studied. The rural population of Kyrgyzstan has the following demographic characteristics: (1) it is demographically young (the population mean age is 25-28 years); (2) the sex ratio in reproductive age groups is unfavorable; (3) the fertility is high (5.78-7.68 pregnancies and 4.27-5.20 surviving children per woman of postreproductive age; (4) interethnic marriages are rare (1.0-5.9%), whereas consanguineous marriages are frequent (1.4-12%); (5) Crow's indices are relatively low (I(tot) = 0.24-0.29, I(m) = 0.05-0.13, I(f) = 0.14-0.22); and (6) both male and female contributions of different regions of the republic make unequal contributions to the gametic structure of the population, with the gametic structure varying from generation to generation. Demographic parameters vary in rural populations of different geographic regions and with different ethnic compositions.
