How many people speak Mexican spanish?

It's not accurate to say "Mexican Spanish" because it's not a separate language. Spanish is spoken in many countries, and each region has its own dialect, including Mexico.

To answer your question, it's better to ask "How many people speak Spanish?"

According to the Cervantes Institute, there are over 570 million native Spanish speakers worldwide, with Mexico having the second-largest Spanish-speaking population after the United States.

It's difficult to get an exact number for speakers of Mexican Spanish specifically, as it overlaps with other dialects within Mexico and across borders.
