All data in this website comes from the Mexican Justice System, in addition the government health agencies track the number of homicides, but that information is updated much less frequently. If you use the data I would appreciate a link back. Some states may be missing from the municipio data because they haven't reported their data, if this happens wait a couple of days to download the data again.
