Unsafe places in Mexico City include Iztapalapa, Tepito, Neza, Ecatepec, and Doctores. In fact, the crime statistics you may find online about Mexico City are mostly exclusive to these areas. Doctores has made an improvement in terms of safety in the past couple of years, but I’d still avoid the area, just in case. Moreover, Neza is the neighborhood Benito Juarez International Airport is located in, so you will be there if you fly into Mexico.
