Crime in Mexico has reached critical levels, particularly in Mexico City. There's been a marked increase in the level of violence and a significant incidence of sexual assault in crimes committed against women. The most frequently reported crimes involve taxi robberies, armed robbery, metro robbery, pickpocketing and purse snatching. Credit-card fraud and ATM robbery are also prevalent.
Travelers to Oaxaca and Chiapas should restrict their itineraries to the main tourist routes, maintain a high level of personal security awareness and contact their embassy in Mexico City before traveling to these sometimes violent states. Popocatépetl's volcanic activity should also be monitored.
