[Genetic demographic parameters of the marriage structure of the Yevpatoria population]

Records on marriages contracted in the city of Yevpatoria, Ukraine in 1960/1961, 1985, 1993, and 1994/1995 were used to determine some parameters of the city population structure. The coefficients of correlation with respect to the age of marriage in reproductive-age couples contracting marriages in these years were 0.77, 0.81, and 0.80, respectively. Women that contracted marriages at reproductively unfavorable ages (under 20 and over 30 years) in the respective years constituted 28.3, 40.6, and 45.4% of the total sample. The proportions of interethnic marriages in these years were 39.4, 43.9, and 46.6%. The proportion of Slavs decreased from 94 to 91% during 35 years, but the proportion of Ukrainians increased from 23.1 to 26.5%. The proportion of other ethnic groups (Tatars, Armenians, Karaites, Poles, Germans, etc.) increased from 3 to 8.6%. The marriage contingency with respect to ethnicity (K = 0.26 in 1960/1961, K = 0.22 in 1985, and K = 0.28 in 1994/1995) was higher than with respect to education (K = 0.18 in 1985 and K = 0.23 in 1993) or occupation (K = 0.18 in 1960/1961, K = 0.17 in 1985, and K = 0.23 in 1994/1995). The marriage assortativeness with respect to ethnicity was the highest in ethnic minorities (A' = 55.1%); that with respect to education, in persons who had higher or primary education (A' = 40.1% and A'= 78.0%, respectively); and that with respect to occupation, in students, military personnel, and production workers (60.6, 58.7, and 30.9%).
