The Immigration Professors Blog reports some interesting recent research on the impact of immigrants in a handful of “Super Tuesday” states.

Arizona: A 2007 study by the University of Arizona's Udall Center for Studies in Public Policy concluded that “the total state tax revenue attributable to immigrant workers was an estimated $2.4 billion-even balanced against estimated fiscal costs the net 2004 fiscal impact of immigrants in Arizona was positive by about $940 million.”

Arkansas: A 2007 study by the Urban Institute found that “…without immigrant labor, the output of the state's manufacturing industry would likely be lowered by about $1.4 billion-or about 8 percent of the industry's $16.2 billion total contribution to the gross state product in 2004.”

New York: A 2007 study by the Fiscal Policy Institute concludes that New York's immigrants are responsible for $229 billion in economic output in New York State or 22.4 percent of the total New York State GDP.

Georgia: A 2006 study by the Georgia Budget and Policy Institute estimated that an average undocumented family in Georgia contributes between $2,340 and $2,470 in state and local sales, income, and property taxes combined.
