I believe data shows 3 million people have fled Venezuela in the past few years up until now. I looked it up, Venezuela has a population of around 30, 33 million or so. So, this is close to 10% of the population. Also, to put that in retrospect, that percentage applied to the US would be around, say, 30 million people.
Also, these refugees have fled to Colombia, Brazil and then, to a lesser extent, Ecuador and Peru. So, it sounds like a regional crisis definitely.
