    Abstract:
    The age limits of the female reproductive function, vital statistics, and Crow's indices were estimated in populations of three districts of the Tuva Republic that were remote from one another. These were the Kyzyl (the Shinaan population), Todzhinskii, and Bai-Taiginskii raions. The monoethnic Shinaan population was characterized by the longest reproductive period (15.88 years) but the lowest average number of pregnancies throughout the reproductive period (5.77); childbirth was an outcome of 86.72% of pregnancies. In the Bai-Taiginskii population, which was also monoethnic but lived in an industrial area of Tuva, these parameters were 12.99 years, 7.06 pregnancies, and 81.97%, respectively. The Todzhinskii population, which was ethnically mixed, exhibited the shortest actual reproductive period (10.72 years) and the greatest average number of pregnancies throughout the reproductive period (7.29), with the proportion of pregnancies ending in childbirth as low as 48.30%. The indices of potential selection and their components related to differential mortality and differential fertility were the following: in the Shinaan population, Itot = 0.59, Im = 0.19, and I(f) = 0.34; in the Bai-Taiginskii population, Itot = 0.48, Im = 0.18, and I(f) = 0.26; and in the Todzhinskii population, Itot = 0.90, Im = 0.23, and I(f) = 0.55. Thus, reproductive parameters in the studied populations of the Tuva Republic were largely determined by the ethnic composition of the population and social factors.
