title: [Temporal dynamics of ethnic assortativeness in the Tsivil'sk region of Chuvashia].
abstract: Based on marriage records for 1950-1959, 1970-1979, and 1990-1999, ethnic assortativeness of Chuvash and Russian inhabitants of Tsivil'sk raion of the Chuvash Republic was calculated. It was shown that in half a century ethnic assortativeness of Chuvashes did not change (1.18, 1.15, and 1.15), while in Russians a clear downward trend was observed (4.20, 2.18, and 1.28). The data on ethnic assortativeness obtained were compared with those for the same populations from other regions of the Chuvashia examined earlier.
