Not just Cubans, either – after the refugees got their Miami community established, Miami became an attractive destination for Mexicans, Dominicans, etc., etc. Plus a substantial Haitian minority. (All county government publications are printed in English, Spanish, and Creole.)
And having lived there I assure you, even if you’re just visiting or passing through, that is a fact impossible to ignore. Unless you’re watching TV shows or films set in Miami, such as Burn Notice or Miami Vice. Then the Latinos remain ubiquitous, yet they still become somehow . . . marginal, as they would be in even a Latino quarter of NYC or LA. Well, in Miami they ain’t marginal, they run the whole show.
I’m not sure either show is really going for verisimilitude. Although it’s interesting to speculate whether Burn Notice, which was originally set in Newark, New Jersey, would have ignored the large Black population there.
I’ve never paid much attention, but thinking about it now, there are quite a few Latinos in Dexter which takes place in Miami. Not just as regular cast members, but also as extras (in background shots) as well people with random single lines or one off characters in single episodes.
IIRC, *Dexter *has a lot of Latino characters, some of them pretty high up like the police lieutenant and the character that Jimmy Smits played. (I think he was the DA?)
