A new analysis from the Center for Immigration Studies estimates the U.S. will see a record-high surge in legal immigration within the next decade if the immigration bill being debated this week in the Senate passes.
The study, expected to be released later Monday, predicts that by 2020, the foreign-born share of the population would have more than tripled to 16 percent from 4.7 percent in 1970.
The findings, based on data from the Congressional Budget Office, also project that the foreign-born population would tick up even higher to 17 percent by 2033, the highest level ever in U.S. history. The study projects that the size of foreign-born population would not stabilize under the Senate "Gang of 8" bill and would continue to increase significantly.
The total size of the U.S. population is expected to hit 351.8 million in 2013 and 381.5 million by 2033 – which comes out to more than a 72.8 million increase over the 2010 census. That includes the entire population, not just those who are foreign born.
Last week, the CBO and the Joint Committee on Taxation projected that if Senate bill 744 passes, it would generate changes in spending and revenues that would decrease federal budget deficits by $197 billion between 2014-2023.
