* Lack of Comprehensive Data: There's no official, nationwide census that specifically asks about bilingualism.
* Definition of Bilingualism: What constitutes bilingualism? Does it mean fluency in both languages, or simply understanding and speaking both?
* Regional Variations: Bilingualism rates vary significantly depending on the region. For example, areas near the US border have higher rates of English speakers than those in the interior.
However, we can look at some estimates:
* Around 10% of the Mexican population is estimated to be fluent in English. This is based on various studies and surveys conducted over the years.
* Indigenous languages are spoken by a significant portion of the population. There are over 60 indigenous languages spoken in Mexico, with some estimates suggesting that up to 10% of the population speaks an indigenous language as their primary language.
It's safe to say that bilingualism is common in Mexico, but providing an exact percentage is challenging.
