An estimated 6.3 million illegal immigrant families lived in the United States in 2004. A significant share had "mixed status": One or more parent was illegal, while one or more child was a U.S. citizen by birth.
The Pew Hispanic Center reports there are more than 10 million illegal immigrants in the U.S. This population is spreading out from the states with traditionally high immigrant populations.
Many Hispanics arrive in places like California, Florida or Texas-but are now moving to Midwestern towns.
One of the main findings of the Pew report is a growing number of mixed-status families, where some members are legal, and some are not. A community in Kansas illustrates the report's findings.
