page 14: "Migratory movements between pairs of countries are referred to as “bilateral corridors”. The
largest bilateral corridor in 2017 was that between Mexico and the
United States of America. The latter hosted 98 per cent of all
Mexican-born individuals (12.7 million) residing abroad (figure 8)."

For two decades, 1990-2010, the largest population transfer on earth remained Mexico to the United States:
*1990-2000: US added 5 million Mexicans, 500,000 annually:
(p. 21-23, pdf): "Mexico to USA was the largest bilateral migration corridor in the world, with an annual average of nearly 500,000 migrants born in Mexico being added to the population of the United States of America from 1990 to 2000. Fig. I6" [5 million over ten years] UN chart, page 22, pdf
*2000-2010: US added 2.4 million Mexicans, 240,000 annually:
page 23, pdf: "During the period from 2000 to 2010...Mexico-USA continued to be the corridor with the largest gain--on average, around 240,000 additional migrants per year."
de facto open borders reflecting the "heart" of those demanding an
endless flow of cheap labor, the US political class continues to be the
safety valve for tyrannical and incompetent governments around the
world. Such governments have no incentive to change as long as US taxpayers are offered up as global slaves.
