Surprise, surprise; Census Bureau data reveals that most U.S. families headed by illegal immigrants use taxpayer-funded welfare programs on behalf of their American-born anchor babies.Even before the recession, immigrant households with children used welfare programs at consistently higher rates than natives, according to the extensive census data collected and analyzed by a nonpartisanWashington D.C. group dedicated to researching legal and illegal immigration in the U.S. The results, published this month in a lengthy report, are hardly surprising.Basically, the majority of households across the country benefitting from publicly-funded welfare programs are headed by immigrants, both legal and illegal. States where immigrant households with children have the highest welfare use rates are Arizona (62%), Texas, California and New York with 61% each and Pennsylvania(59%).The study focused on eight major welfare programs that cost the government $517 billion the year they were examined. They include Supplemental Security Income (SSI) for the disabled, Temporary Assistance to Needy Families (TANF), a nutritional program known as Women, Infants and Children (WIC), food stamps, free/reduced school lunch, public housing and health insurance for the poor (Medicaid).Food assistance and Medicaid are the programs most commonly used by illegal immigrants, mainly on behalf of their American-born children who get automatic citizenship. On the other hand, legal immigrant households take advantage of every available welfare program, according to the study, which attributes it to low education level and resulting low income.The highest rate of welfare recipients come from the Dominican Republic (82 %), Mexico and Guatemala (75%) and Ecuador (70%), according to the report, which says welfare use tends to be high for both new arrivals and established residents.
