Epidemiology is a branch of medicine that studies the prevalence of diseases and epidemics and their early detection and prevention. In order to monitor the course and occurrence of diseases of interest for epidemiology, mortality statistics is one of the most reliable health-statistical indicators. Diseases can be monitored by various epidemiological measures of frequency and association. One of the main measures used in this paper is proportional mortality, to show the mortality rate of some causes of death in the mortality of the total population, for a more accurate and easy monitoring and for the analysis of the causes of death itself. In this paper the analysis of mortality, or diseases as a cause of death, was carried out in Bakar and its vicinity in the period from 1972 to 1981. The causes of death are ranked by the main groups of the tenth revision of the International Classification of Disease. The leading causes of death are chronic non-contagious disease, precisely deseases from the circulatory system with 51% and neoplasms with 21% of the total number of deceased, over a decade, which completely fits with today's trend of the most common causes of death in the developed part of the world. It has been observed that chronic non-contagious diseases, which today represent the world's largest public health problems, have already been increasing in the processed period. Today, many programs and action plans are launched locally and globally to prevent and control the consequences of chronic massive diseases.
