Virtually all immigrant families with four or more children in the house are on some type of welfare program, according to U.S. Census Bureau data in a new report raising questions about those Washington is letting into the country.

In the data analyzed by the Center for Immigration Studies, 93.7 percent of all immigrants — legal and illegal — accessed welfare, mostly free school lunches, in 2012, the latest year for new data. For “native” American families with four or more children, the number was 69.4 percent.
