Indicators characterizing population migration were calculated according to the marriage records of Yevpatoria (Crimea) of 1960/1961, 1985, and 1994/1995. The marital migration coefficient m in those years was 0.80, 0.75, and 0.66, the endogamy index was 0.04, 0.08, and 0.15, and the rate of marriage contingency by birthplace was 0.15, 0.16, and 0.19, respectively. The highest values of the positive mating assortative index were recorded for people from the Caucasus, Central, Central Black Earth Oblast, and Northwest regions of Russia in 1960/1961 and for migrants from Moldavia, the republics of Central Asia and Caucasus, Western Siberia, and Ukraine in 1985. In 1994/1995, natives of Yevpatoria were also included in this group. The average distance of migration by year was 909, 1280, and 1314 km, and the marital distance was 960, 1397, and 1171 km. The “radius” of the Yevpatoria population, in accordance with the Maleco model in the years under study, was 98, 134, and 137 km. The distance isolation indicator b was decreasing and amounted to 0.00049, 0.00043, and 0.00038. In the migration flow in all of the periods, the majority of immigrants came from different regions of Ukraine outside Crimea (27–31%), followed by natives of various places in Crimea (21–24%), Central (3.6–8.5%), and Central Black Earth (1.8–6.1%) regions of Russia, and the South Caucasus (4.0–5.7%). The proportion of Russians and Jews decreased in the migration flow, while the proportion of Ukrainians and representatives of non-Slavic nationalities increased.
