According to data from the U.S. State Department, the first six months of 2011 represented the most deadly period of the past eight years for U.S. citizens in Mexico.

From January 4 to June 11 of this year, 65 Americans were killed in Mexico, a 300 percent increase since 2003. This figure comes from La Opinion, which gained access to a report compiled by the U.S. State Department. As the paper notes, the actual number of deaths may be higher in reality, as the figures only refer to voluntarily reported deaths.

Still, the numbers reveal some noteworthy patterns about the most dangerous places, statistically, for Americans in the country. The report found that Baja California, Tamaulipas, Chihuahua, Sonora and Sinaloa have been the site of most of the violence, with a third of the deaths occurring in the border cities of Ciudad Juarez and Tijuana.

In its most recent travel advisory, issued on April 22, the State Department also warned U.S. citizens to exercise extreme caution when traveling to the states of Michoacán, Durango, Zacatecas, San Luis Potosí, Guerrero and Jalisco. Nevertheless, the State Department warning points out that “there is no evidence that U.S. tourists have been targeted by criminal elements due to their citizenship,” a reminder that attacks on Americans are usually opportunistic, and not systemic in nature.
