The Gallup Poll reports based on surveying 452,000 people in 151 countries in 2009-2011:

150 Million Adults Worldwide Would Migrate to the U.S. Potential migrants most likely to be Chinese, Nigerian, and Indian by Jon Clifton WASHINGTON, D.C. — About 13% of the world’s adults — or more than 640 million people — say they would like to leave their country permanently.

Of course, 640 million adults wanting to emigrate does not included their dependent children and dependent elders. So, that’s more like a billion or so.

Roughly 150 million of them say they would like to move to the U.S. — giving it the undisputed title as the world’s most desired destination for potential migrants since Gallup started tracking these patterns in 2007.

We’re Number One! We’re Number One!

Keep in mind that America is the first choice of 150 million adults, but, presumably, an Open Borders policy in the U.S. unmatched by other Anglosphere countries would also lure in many of the 113 million whose first choices are UK, Canada, and Australia.

Of course, not all these people would show up, since life in America would get increasingly crummy the more the tens of millions of Third Worlders move in, so a balance would be reached where life in America isn’t better than back home in the Third World long before all potential immigrants arrive.

In addition to the nearly one in 30 adults worldwide who would like to permanently relocate to the U.S., large numbers are attracted to the United Kingdom (45 million), Canada (42 million), France (32 million), and Saudi Arabia (31 million). Gallup’s latest findings on adults’ desire to move to other countries are based on a rolling average of interviews with 452,199 adults in 151 countries between 2009 and 2011. The 151 countries represent more than 97% of the world’s adult population. Who Wants to Move to the U.S.? Potential migrants who say they would like to move to the U.S. are most likely to come from populous countries such as China (22 million), Nigeria (15 million), India (10 million), Bangladesh (8 million), or Brazil (7 million). … Gallup found that more than three in 10 adults in Liberia (37%) and Sierra Leone (30%) would move permanently to the U.S. if they had the opportunity. More than 20% of adults in the Dominican Republic (26%), Haiti (24%), and Cambodia (22%) also say the same.

In reality, that’s just the first wave. With Open Borders, there’s no limit to how many would come over time.* For example, something like 2/3rds of Puerto Ricans now live in the 50 states despite lavish subsidies intended to keep them at home.

* Except that the Third Worldification of the First World receiving country would eventually set a limit be reducing the receiving country to the level of the Third World sending country.
