*Occupations included in the Top 20 Occupations with High Shares of Immigrants in the United States Illegally table have at least 100,000 workers nationally and more than three times the national share of unauthorized immigrant workers.
**"Unauthorized" occupations have a higher percentage of workers who are unauthorized immigrants than the national average but do not qualify for a separate listing.
According to the Congress of the United States Congressional Budget Office's Nov. 2005 report "The Role of Immigrants in the U.S. Labor Market":
"Considerable uncertainty is inherent in estimates of the number of unauthorized immigrants that reside in the United States and the number that are in the labor force. The decennial census, the Current Population Survey (CPS), and similar sources of information about the population and labor force do not ask foreign-born people about their legal status in the United States aside from whether they are naturalized citizens. Thus, the number of unauthorized immigrants must be estimated by indirect methods that introduce the possibility of significant errors. A recent analysis, based on survey data from the CPS and administrative data from the Department of Homeland Security and other federal agencies, indicated that in early 2004 about 10 million foreign-born people were living in the United States without authorization and about 6.3 million of them were in the labor force."
