Answer 2

Those would be:

Mexico City (20.14 million) - the economic, political and cultural capital of Mexico. Think of it as the equivalent to a mixture of New York City and Washington, D.C.

Guadalajara (4.43 million) - the largest city on western Mexico and second in the country; with hundreds of years of colonial history and a technology corridor, it is dubbed as the "Mexican Silicon Valley".

Monterrey (4.08 million) - the largest city in northern Mexico, considered the heart of the Mexican industry. It has the biggest income per capita in Mexico (USD 22,191) - say, bigger than that of Portugal, Greece or Taiwan.
