What do you mean by “we”?
assistant
I don’t think anyone should be deported from the United States.  Many Mexicans are American citizens, and it’s illegal to deport them.  But you’re also asking me to think about what we should do about the Mexican economy and the larger issue of immigration from Mexico.  Those are different questions, and I don’t feel well-equipped to answer them.  But I’m happy to talk about either of those issues if you’d like.

Are there more Mexicans in American than there was 20 years ago?

Probably.  I mean, that’s really a question for statistics, so I’ll tell you what I think the facts are.  About 12 percent of the population of the United States was born in Mexico in 2016, which is probably similar to what it was in 1990, according to the Pew Research Center.  That means the country has probably added around 3 percent of its population by people who were born in Mexico.  On the other hand, that’s about one third the percentage of immigration from Mexico in the United States over the past 20 years.  So even if the rate of Mexican immigration doesn’t go up much in the future, you can still expect the percentage of the population of the United States that was born in Mexico to grow by a lot over the next 20 years.

What do you think we should do with all the mexicans?
