The statistics of mortality are used in epidemiology and public health as an indicator of health is the most important source of information about population health supporting health policy more efficiently and effectively. The aim of this study was to describe the evolution of overall mortality, infant, by gender, age, and cause group in Santa Maria - RS, during 1998 to 2007. For this were calculated the mortality rates, and was adjusted a simple linear regression model. Information was obtained from BCs and DCs recorded in the Brazilian National Live Birth Database (SINASC) and Death Database (SIM), respectively, included in the Brazilian National Health System Database (DATASUS). The results showed that the major causes of infant mortality and general were, respectively, certain conditions originating in the perinatal period and diseases of the circulatory system. The temporal evolution of the coefficients for gender indicated that mortality rates are decreasing among men but increasing among women. Regarding age groups, we found that infant mortality is not significantly decreased, and aged 80 years and over there is a significant increase. According to analysis of mortality by group of causes it was observed that circulatory diseases are declining significantly. It is hoped that the results could contribute to the health managers of the municipality to detect critical points in question and can base their decisions to reduce mortality rates that remain high.
