As immigration is becoming a hot and rather sensitive topic during the campaign, statisticians are launching various predictions as how the country might look in the future in terms of variety. In 2012, 8.4 percent of the U.S. resident adult population was the child of someone born outside the country, and 4.5 million children born in the United States (6.1 percent of the population under 18) lived with at least one undocumented parent, if not both.
First generation immigrants are those born outside the U.S. who came to the country legally or illegally, while their children are considered second generation. 15.9 percent of the adult population was first generation in 2012, according to the Pew Research, whereas 8.4 percent was second generation. Considering these numbers, as well as the immigration pace, by 2050, 36.9 percent of the population is expected to be first and second generation immigrants, each category in equal shares.
The same research also revealed that parents of immigrants who gave birth to a child in the United States have lived in the country longer than those who don’t have children.
