More errors in the Mexican Mortality Database

on Sep 12, 2012

I've written before about how the deaths of the Acteal massacre weren't registered as homicides in the mortality database and about the large number of deaths of unknown intent in Ciudad Juárez. There's actually another large error in the database that occurred in January and February of 2007. Lots of accidents of unspecified injury mechanism were registered in the Federal District at the same time there was a never before seen drop in the number of homicides.

Violence along Mexico's Southern Border and Central America

Rates for Panama and Nicaragua are from 2009, all other countries 2010. Municipalities which are part of a metro area in Mexico are shown with the metro area homicide rate.

Having just posted on violence along Mexico's northern border, I figured it's time to analyze what is happing south of Mexico where some countries have experienced sharp increases in homicides.

Homicides along the United States–Mexico border

on Sep 4, 2012
The drug war in Mexico has increased the homicide rate in several parts of the country, but one of the most affected regions has been those areas near the U.S. border.
Sources: CDC / INEGI. For Mexican municipalities the distance to the border was measured from the main locality of each municipality, for US counties the distance to the border was measured from the centroid.
Violence has generally stayed on the Mexican side of the border. The trend in homicides for all U.S. counties at least 160 km from the Mexican border has been downward since the drug war started.
Sources: CDC / INEGI
Keep in mind that violence in Mexican municipalities at least 160km from the border was lower in 2006, when the drug war started, than in 1999.

P.S. When referring to homicides in the US I included those deaths that were the result of legal interventions since in Mexico police/military interventions are usually counted as homicides.
