Mortality is one of the demographic indicators that determine the direction of socio-economic development of some area. So, this paper analyzes mortality and some of its features in the area of the City of Mali Lošinj in the period from 1960 to 1990. In that transition period, the population of the Lošinj archipelago faced numerous challenges, such as the migration of the young population to the mainland parts of Croatia and other countries, and consequently the aging process of the population. The paper analyzes the data from the mortality database of the area of the City of Mali Lošinj by the methodology - descriptive epidemiology. A total of 2588 persons died in the total thirty-year period, of which 1470 deaths were women (57%) and 1118 deaths were men (43%). The paper presents the mortality characteristics of the residents of the Nursing home "Marko A. Stuparić" in Veli Lošinj. In the observed thirty-year period, a total of 393 persons died who had resided in that specific social - health institution. Of these, there were 280 women (71%) and 113 men (29%). The leading causes of death were the diseases in circulatory system and the neoplasms with 47.14% and 13.36% of the total number of deceased, which completely fits in today's trend of the most common causes of death in the developed part of the world.
