The 35.2 million immigrants (legal and illegal) living in the country in March 2005 is the highest number ever recorded -- two and a half times the 13.5 million during the peak of the last great immigration wave in 1910.
Between January 2000 and March 2005, 7.9 million new immigrants (legal and illegal) settled in the country, making it the highest five-year period of immigration in American history.
Nearly half of post-2000 arrivals (3.7 million) are estimated to be illegal aliens.
