Migrant studies counter negative images

A study released Tuesday by the Public Policy Institute of California found that immigrants who arrived in the state between 1990 and 2004 increased wages for native workers by an average 4%.

UC Davis economist Giovanni Peri, who conducted the study, said the benefits were shared by all native-born workers, from high school dropouts to college graduates, because immigrants generally perform complementary rather than competitive work.

As immigrants filled lower-skilled jobs, they pushed natives up the economic ladder into employment that required more English or know-how of the U.S. system, he said.

"The big message is that there is no big loss from immigration," Peri said. "There are gains, and these are enjoyed by a much bigger share of the population than is commonly believed."

Another study released Monday by the Washington-based Immigration Policy Center showed that immigrant men ages 18 to 39 had an incarceration rate five times lower than native-born citizens in every ethnic group examined. Among men of Mexican descent, for instance, 0.7% of those foreign-born were incarcerated compared to 5.9% of native-born, according to the study, co-written by UC Irvine sociologist Ruben G. Rumbaut.

Both studies are based on U.S. census data, which includes both legal and illegal immigrants. They were released just days before the U.S. Congress is to restart debate on major immigration reform legislation and as numerous states, including Texas, consider harsh measures against illegal migrants.

The authors say their work shows that immigrants clearly benefit U.S. residents and are being unfairly scapegoated for problems they do not cause.

"There are grossly distorted perceptions between what people think about immigrants and the reality," Rumbaut said. "The old bromide that education is the way to reduce prejudice comes into play here."

Immigration hawks, however, took issue with both studies.

Steven Camarota of the Washington-based Center for Immigration Studies said the wage study, by examining immigrants only in California, failed to consider their effect on the rest of the country. Immigrants working for lower wages in a California factory, for instance, could keep wages down in a competing enterprise staffed by native-born citizens in another state, he said.
