Currently, 1.6 million legal and illegal immigrants settle in the country each year; 350,000 immigrants leave each year, resulting in net immigration of 1.25 million.
If immigration continues at current levels, the nation's population will increase from 301 million today to 468 million in 2060 — a 167 million (56 percent) increase. Immigrants plus their descendents will account for 105 million (63 percent) of the increase.
The total projected growth of 167 million is equal to the combined populations of Great Britain, France, and Spain. The 105 million from immigration by itself is equal to 13 additional New York Cities.
