In the speech, he said it was a 2000% increase in immigration in a small town. So if that town has something like 2 immigrants in a decade (probably a pretty realistic number), then that means there were probably a handful of immigrants in that year (2000% of 0.2 is 4).

So if it's true, it's likely wildly misleading.

I kinda wish it were true because imagine all of the amazing restaurants that would be popping up across the country with so many immigrants!
