The United States has more immigrants than any country in the world, four times the next immigrant destination of Germany, according to the latest Pew Research Center report.

Pew reports that 46.6 million living in the U.S. are immigrants. That is about one in five of all international migrants as calculated by the United Nations.

"By a wide margin, the U.S. has more immigrants than any other country in the world. As of 2015, the United Nations estimates that 46.6 million people living in the United States were not born there. This means that about one-in-five international migrants (19%) live in the U.S. The U.S. immigrant population is nearly four times that of the world's next largest immigrant destination – Germany, with about 12 million immigrants," said Pew.

Its latest report includes an eye-catching interactive map that shows the growth of international immigration.

Not surprisingly, Pew said that the busiest immigration area is along the Mexican border.

"The U.S.-Mexico migration corridor is the world's largest. Pew Research Center has extensively studied and attempted to quantify the historic migration route between the U.S. and Mexico. About 12 million people living in the U.S. were born in Mexico," said Pew.

The research and survey outfit put the total world immigrant population at 244 million which, if put together, would be the world's fifth largest nation.
