It is not surprising that Mexico stands out with a great advantage among the first ten countries exporting cheap labor to that country. Not only is it numerically ahead of Guatemala, tenth on the list, by almost 11 million, but it is also a little over 9.5 million ahead of second place, which is occupied by the aggregate of China, Hong Kong and Taiwan. But if we consider the Asian countries as a whole, their total migration to the United States amounts to just over eight million people.

It should also be noted that the sum of the Central American and Caribbean countries, all of which are small in size, together account for slightly more than four million people. Viewed by regions of the world, then, Latin America clearly stands out as the most important producer of migrants for the United States, with 53.1% of the total, followed by Asia, with 28.23%, and Europe, distantly located, with 10.71%. Other parts of the world account for 6.58%.

From Latin America, with a large quantitative advantage, Mexico stands out with 55.18%. The small countries of Central America and the Caribbean, on the other hand, provide a little more than 27% and the rest comes from various South American countries, whose migrants have a much more diversified mobility, especially to Europe. In the case of Latin America and Mexico in particular, there are historical, economic, social, demographic and cultural reasons.
