A new report from the Department of Homeland Security's Office of Immigration Statistics says Texas is the second-most-popular destination for illegal migration.
Only California is home to more illegal workers and residents. Florida rounds out the top three spots.
According to Homeland Security, about 11 million illegal immigrants were living in the United States at the start of 2006. That's up from an estimated 8.5 million just six years ago.
The ranks of illegal immigrants are swelling at a rate of about 408,000 per year. Of the 11 million, about 6 million come from Mexico.
The states with the fewest illegal immigrants, in order: Wyoming, Montana, North Dakota, South Dakota, Alaska, West Virginia, New Hampshire, Vermont and Maine.
