Homeland Security estimates of unauthorized immigrants January 2005

This study has some useful information about the size of the unauthorized population and the geographic origins. For the first time I see a figure indicating a rapid increase in the number of unauthorized Indians.
The study does not address the number of unauthorized workers. My guess is that a very high percentage of all of these immigrants are working, especially recent arrivals who probably do not come with families. For instance, the 2005 total figures for Mexicao and El Salvador are equal to 5.6% and 7.0% of their respective populations at home. I suspect that the American-based numbers represent more like 7.5% and 10% of the home workforces.
The study estimates the January 2006 figure at “nearly 11 million”, having risen by and “annual average” of 408,000 in the 2000-2004 period. The figure for January 2005 is 10.5 million.
Those within the 10.5 figure came to the U.S. in these time frames:
1980-1984 10%
1985-1989 11%
1990-1994 20%
1995-1999 30%
2000-2002 20%
2003-2004 9%
It estimates that 1/1/05 there were 27,320,000 foreign born ….10,500,000 of these being unauthorized.
