The actual size and the origin of the Illegal immigrant population in the United States is uncertain and hard to ascertain because of difficulty in accurately counting individuals in this population. National surveys, administrative data and other sources of information provide inaccurate measures of the size of the illegal immigrant population and current estimates based on this data indicate that the current population may range from 7 million to 20 million.
An often used number in 2008 is 11 million. This is a decline from the historic peak of 12.5 million seen in 2007.[1]
