How Many Illegal Aliens?
FAIR estimates that in 2007 the illegal alien population is above 13 million persons. Government and academic estimates indicate that as of 2006 there were 11 to 12 million illegal aliens living in the United States. The Center for Immigration Studies estimated the illegal alien population at 10 million as of November 2004. It is difficult to have an exact figure because the illegal nature of their presence prevents any enumeration, but the U.S. Census Bureau estimated 8.7 million illegal aliens were here in 2000, and immigration officials estimate that the illegal alien population grows by as many as 500,000 every year.
