The article compares city (Pro-aim), state (Fundação Seade) and federal (Ministério da Saúde) data for homicides of residents in Sao Paulo city between 1996 and 2000; and Pro-aim and Fundação Seade data for homicides per district in Sao Paulo municipality, in 2000. As homicides were considered deaths caused by assault, legal intervention and events of undetermined intent caused by firearm discharge and contact with sharp or blunt objects. The difference between Fundação Seade and Ministério da Saúde data is worthless. But the difference between Pro-aim and Fundação Seade numbers for homicides of residents in Sao Paulo city in 2000 has statistical significance for a large number of districts. Furthermore, Pro-aim does not record deaths of residents in Sao Paulo city occurred in other cities. Analysis of homicide rates per district in Sao Paulo city that uses Pro-aim data can lead to different results than analysis that uses Fundação Seade data.
