Notes
Homicide rate (WHO): Age-standardized homicide rate per 100,000 people
Homicide rate (UNODC): Intentional homicides per 100,000 people
Access to homicide data from the health system: National websites with data from the health and criminal justice systems were selected based on three criteria. The first is that the data is official, so that the records without validation of the public power are excluded. The second criterion is that the sites provide databases or, at least, online consultation devices through interactive tables or graphs. This excludes specific reports that report data in non-reusable formats (for example, pdf) for users. The third criterion is that the data make possible some level of analysis (sex, age, municipality, etc.) superior to the simple description of time series with aggregate data of homicide.
Access to homicide data from the criminal justice system: The homicide ratio relates the UNODC and WHO data through a quotient. The former are based fundamentally on criminal records, while the latter are derived from death certificates. A ratio of 1 indicates that the number of homicides of both sources is similar, while higher ratios indicate that the number of homicides is higher in the UNODC data, and lower ratios than the number of homicides is higher in WHO data. Thus, for example, a homicide ratio equal to 2 would mean that there are twice as many homicides for UNODC in relation to WHO; while a ratio equal to 0.5 would represent the opposite.
Sources: WHO data were extracted from the WHO Mortality Database (http://apps.who.int/healthinfo/statistics/mortality/whodpms/) and the UNODC data from the UNODC STATS (https: //data.unodc .org /)
