The United States admitted more legal immigrants from 1991 to 2000, between ten and eleven million, than in any previous decade. In the most recent decade, the 10 million legal immigrants that settled in the U.S. represent roughly one third of the annual growth, as the U.S. population grew by 32 million (from 249 million to 281 million). By comparison, the highest previous decade was the 1900s, when 8.8 million people arrived, increasing the total U.S. population by one percent every year. Specifically, "nearly 15% of Americans were foreign-born in 1910, while in 1999, only about 10% were foreign-born."
