Question: what is the current state of immigration in the united states?
Answer: The U.S. foreign-born population reached a record 44.4 million in 2017. Since 1965, when U.S. immigration laws replaced a national quota system, the number of immigrants living in the U.S. has more than quadrupled. Immigrants today account for 13.6% of the U.S. population, nearly triple the share (4.7%) in 1970.
