A key concern that some have regarding (illegal) immigration is the impact it has on jobs for citizens. Recent studies provide some data about the impact. A story in the Los Angeles Times (February 28, 2007) titled “Immigrants boost pay, not prison populations, new studies show” provides some information. Regarding pay, for example, they report:

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%.

The full report on which this part of the story is based, authored by Giovanni Peri and titled How Immigrants Affect California Employment and Wages [pdf], is available here.

Regarding immigrants and crime, the LA Times reports:

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.

The orginal study was published by the “Immigration Policy Center” and is titled “The Myth of Immigrant Criminality and the Paradox of Assimilation: Incarceration Rates among Native and Foreign-Born Men” [pdf].
