What cities in Mexico speak English?

Answer 1

None. All of them have Spanish as their de factolanguage. However, border states, as well as industrial regions (Mexico City, Guadalajara, Monterrey, Queretaro) tend to have more people who can speak English and other foreign languages, due to business reasons.

Answer 2

None or all, depending on your point of view:

None because there is no official language and 92.7% of the population speaks Spanish as their mother tongue, while 5.7% speak Spanish AND any Amerindian language such as Nahuatl or Mayan. This leaves less than 1.8 million people throughout people who speak anything besides those languages.

All because many people troughout the country speak English, and they are English-speaking immigrants, many residents on the northern border states of Mexico and many people who use it on a daily basis for business and tourism activities.
