Pneumonia is an inflammatory process of lung parenchyma, being one of the ten first causes of death in developed countries. The data for the performance of this study have been obtained from Monografías Sanitarias: mortality statistics published by the Generalitat Valenciana for the five-year period 1976-1980. The distribution of pneumonia was analyzed according to age and sex by means of specific rates and mortality reasons. Furthermore, calculations of standardized rates and standardized mortality rates were carried out using the direct method. The results establish that in Health areas 2, 8, 9-12, 15, 16, 21 and 22 there is an increased mortality due to pneumonia. Similarly, it is note worthy the predominance of pneumonia in older groups, while no significant differences exists between sexes.
