[Marriage migration parameters in six rural districts of Bashkortostan Republic].

The marriage migration structure of the populations of six districts of Bashkortostan Republic has been studied. The rates of assortative marriages in Bashkirs, Tatars, and Russians are 1.02-2.71, 1.30-5.99, and 2.14-7.50, respectively; the endogamy indices are 0.58-0.97, 0.90, and 0.68, respectively. Malecot's isolation-by-distance parameters in Bashkirs, Tatars, and Russians, respectively, are the following: sigma is 6.7-83.0, 40.3-106.1, and 69.9; a is 0.00012-0.00074, 0.00170-0.0029, and 0.00096; and b is 0.0087-0.0467, 0.0038-0.0208, and 0.0129. Changes in these parameters with time have been traced.
