摘要：Demographic research in regard to the islands of Cres and Lošinj belongs in the domain of small population studies. Throughout history, and especially after World War II, the islands experienced very strong emigration and later immigration processes. After fifty or more years of continual emigration, immigration began on the island of Lošinj in the 1960s, and on Cres in the 1970s. This reversal from strong depopulation to a significant increase in the size of the population, if the islands are examined as a whole, reveals certain demographic particularities in comparison with other Croatian islands. The long-term reduction of the birth rate and prolonged emigration from settlements in the interior of Cres and from all the islands of the Lošinj archipelago has been the cause of many elderly, single-person and abandoned households. All the analytical indicators pertaining to the age structure are above the threshold which marks the beginning of population ageing. The average age on all the islands has for over thirty years been well above 30, whereas in the Lošinj archipelago it has been above the reproductive age – i.e. about 50. The age coefficient varies between 14.02 for Lošinj and 49.22 for Ilovik. The island of Lošinj itself has the youngest population, and hence the lowest indicators of ageing. The burden on the working-age contingent on each island has changed at a different rate and in a different direction during the last three inter-census periods. The co-efficient of dependency of the young is increasing on all the islands, while the co-efficient of dependency of the elderly age groups is falling on Lošinj, Ilovik, Unije and Cres. The reduction of the birth rate and the negative migration balance caused by high emigration of mainly young, unmarried males has caused a seks ratio imbalance in favour of females. The general co-efficient of females, according to the 1991 census was between 105.7 on Lošinj and 145.5 on Unije. The co-efficient of females in the over 65 age groups indicates an even greater proportion of women in the population. On the entire Cres-Lošinj archipelago there is only one facility for the institutional accommodation of the elderly.
