Abstract:

The study aims to analyze trends and distribution of homicide mortality rates (HMR) according to population size of Brazilian municipalities between 2000 and 2015. This is an ecological study of deathsthe Mortality Information System, with TMH standardized by the direct method and 95% confidence interval. The TMH in Brazil grew 6% (to 29.1/100,000) in the period, with increase in municipalities of small (83%; 12.7 to 23.2/100,000) and medium-sized (52%; 19.7% to 30.1/100,000); which is true for both sexes, different ages, regions and events by firearm. The TMH decreased in large metropolitan municipalities (19%; 40.6% to 32.9/100,000) and the Southeast region (55%; 45.6% to 20.6/100,000). The relative risk-RR of small and medium-sized cities in relation to large ones is already higher or near 1 in women (RR 0.99; 1.03), people aged 60 years or older (RR 1.43; 1.36) and homicides by other means (RR 1.16; 1.18). The cities of São Paulo and Rio de Janeiro contributed the most to the reduction of HMR, especially in large cities (-37.6 and -22.3 homicides/100,000 inhabitants). Municipalities of small and medium size have consistent trends to increase HMR even considering population subgroups.
