The sex structure of Primoryes population is relatively balanced. Males constitute 49.5%, and females 50.5%. However, their ratio for specific age groups strongly varies. In the younger age group, the bulk of Primorye residents are males, who are especially numerous in the 20-35 age bracket to retain their superiority in number till the age of forty. In subsequent years, in connection with greater female life expectancy, the populations sex structure becomes more balanced, and by the age of fifty the number of females is greater. 
 In the 65-70-age bracket, there are two times more females than males. Considerable distinctions are observed in the populations age structure in urban and rural areas. In towns, irrespective of their size, the share of the female population is higher than that of males. The only exception is Nakhodka, where seamen and fishermen (predominantly males) make the male population prevalent. Males are more numerous in rural areas. Then include 50.7% of all rural residents. In some districts (Laso, Pozharskoe), males overbalance females by over 200 per 1,000 females.
Sex structure      The prevalence of the male population over the female population in the younger age groups in Primorye has both positive and negative impacts. On the one hand, shortage of hands in the basic mining sectors strictly oriented to marine transport decreases, but on the other hand this hampers normal marital processes. Many males cannot marry in the settlement where they reside. The problem of brides is particularly acute in mining and agricultural areas, and also in settlements specializing in fishery and fish processing.
