And from the article, over 60% is of Mexican ancestry. So over 30 million versus the population of Mexico at a little over 120 million. Roughly 20% of Mexicans moved to the US.
As recently as 1940, Hispanics made up only 1.5% of the US. Population. As of 2010, they made up 16.3% of the U.S. population (about 50 million people). As a point of reference, Canada has a population of about 37 million people and the UK has a population of 63 million people. So we have imported roughly an entire Canada/UK's worth of people from Latin America. As far as I am aware, immigration of this scale is basically unprecedented in human history.
