People elsewhere in south Florida sometimes sneeringly refer to this place as "Rat's Mouth" (though, as already stated by others, this is an incorrect Spanish translation), due to the presence of an abnormally high number of con men and other white collar criminals in this city, perhaps attracted there by the large number of wealthy retired people ripe for fleecing.
Boca Raton also has the distinction of being the world center for supermarket tabloids, ever since the two leading U.S. tabloid publishers merged and set up their headquarters here. Look in practically any tabloid at your checkout counter, from the National Enquirer to the Weekly World News, and you'll probably see a Boca Raton address in its masthead.
There are also a number of high-tech businesses there, with staffs of young, well-educated professionals, so the population is more diverse than some of the other descriptions would make it seem.
