In a previous post we noted that big Mexican cities with populations of over 500,000 have drug war death rates about 40% higher than the rest of Mexico. However the highest rates of all are in small northern municipalities which have experienced very high levels of drug violence.
Mier, Tamaulipas was the most dangerous municipality in 2011 as it was in 2010. Though the number of drug war deaths in the town of 4,768 (2010) decreased from 93 in 2010 [note 1] to 50 in the first nine months of 2011 [note 2], it still led the country with 1,398 drug war deaths per 100,000/yr [note 3]. This is 91 times the rate for all of Mexico which was 15.3 in 2011 and also over ten times as dangerous as Acapulco, the large city with the highest rate of drug violence. Actually the death rate per population for Mier is probably higher because the mayor estimates that a third of the population may have fled the violence-prone town [note 4]. Mier is only about eight kilometers (five miles) from the Texas border and roughly midway between Nuevo Laredo and Reynosa. The municipality may be a bit more peaceful now that the Mexican military has occupied the town.
Guerrero, Mier’s immediate neighbor to the northwest with a population of 4,468, ranked second with a death rate of 1,045 or roughly 68 times the average. Both Guerrero and Mier are located between two warring drug cartels, the Zetas and the Gulf Cartel. Mier’s other neighbor along the Rio Grande, Miguel Alemán, fared somewhat better. Its death rate dropped from 407 in 2010 to 114 in 2011; but its 2011 rate was still over seven times the national average. The data reveal that municipalities along the border between Nuevo Laredo and Reynosa are among the most dangerous in all of Mexico. Interestingly, the rate for Reynosa itself was only 11 or about 27% below the average.
In third place is San Fernando, also in Tamaulipas, with a death rate of 680, about 44 times the average. This community of 57,220 suffered 292 deaths in 2011. Over half of these deaths were discovered in mass graves of Central Americans who were trying to immigrate to the US, but were kidnapped and murdered by drug cartels.
Next on the list are three small municipalities in Chihuahua – Guadalupe (rate of 496), Gran Morelos (373) and Cusihuiriachi (369). The 2011 death rates in these towns were 24 to 32 times the national average. While the rate for Guadalupe declined 42% since 2010, the rates for Gran Morelos and Cusihuiriachi were up 50% and 150% respectively. As mentioned in an earlier post, the State of Chihuahua had the highest 2011 drug war death rate among Mexico’s 32 states.
Drug war death totals in small communities can change dramatically from year to year. For example, Saric, Sonora with a population of 2,703 had 30 deaths in 2010 and zero in 2011. General Bravo, Nuevo Leon had 18 deaths in 2010 and zero in 2011 while Yecora, Sonora had 18 deaths in 2010 and only one in 2011. The number in General Treviño, Nuevo León went from 21 down to only two, but it still had the 8th highest rate among Mexico’s municipalities.
On the other hand, drug war deaths in Boca del Rio, Veracruz went from 2 in 2010 to an alarming 94 in 2011. This resulted in a rate increase of 6,167% and a rate six times the average. The rate for Zihuatanejo de Azueta, Guerrero increased by 650%; that of Yurécuaro, Michoacán went up by 452% while that for Cosalá, Sinaloa was up 317%, giving it a rate 13 times the average.
Zihuatanejo de Azueta is different than many of the other communities with very high drug war death rates because it has a rather large population of 104,609 and includes the famous international resort of Ixtapa. The number of drug war deaths in the municipality went from 16 in 2010 to a very disturbing 90 in 2011, giving it a death rate of 115, almost as high as Acapulco’s rate of 134. Certainly, the high drug war death rates in Zihuatanejo and Acapulco have damaged their tourism industries.
Twenty municipalities had drug war death rate in 2011 higher than 100 per 100,000/yr or about seven times the national average (see table). Two of these are the large municipalities of Ciudad Juárez and Acapulco. The 20 communities are spread across six northern and western states: six in Chihuahua, five in Tamaulipas, three in Guerrero, two in Sinaloa and Michoacán, and one each in Sonora and Nuevo León. Before randomly traveling in areas of these states, it would be a good idea to check local media and bulletin boards for indications of recent drug violence.

 The rates for 2011 were adjusted because data are available for only the first nine months of the year.
