OBJECTIVE: To describe the level and temporal trends of homicide impunity in Brazil.
METHODS: This is an ecological study that calculated two impunity indexes by dividing the total number of homicides committed in a 5-year period by the number of individuals arrested for murder (homicide impunity) or any other cause (general impunity) two years after this period. The Prais-Winsten linear regression model with serial autocorrelation correction was used to estimate the temporal trend of the impunity indexes.
RESULTS: Between 2009 and 2014, 328,714 homicides were recorded in Brazil, but only 84,539 prisoners were serving sentences for this kind of crime in 2016. This shows that the number of homicides in Brazil exceeded in 244,175 the number of individuals in prisons for this crime. The impunity index ranged from 3.9 in 2006 to 3.3 in 2014. All states reached values above 1. Rio de Janeiro stood out negatively, with values above 20. São Paulo, Santa Catarina, and Distrito Federal showed the lowest impunity indexes for homicide, with values below 2. Eight states showed a downward trend in the overall impunity index.
CONCLUSIONS: Most Brazilian states presented extremely high impunity indexes values. However, from 2010 to 2012, Brazilian society started to effectively combat impunity for serious violent crimes, including homicide. In São Paulo, this positive trend arose in the mid-1990s and that state currently shows impunity indexes values similar to those of developed countries.
