By Gordon H. Hanson

Immigration reform is one of the most divisive issues confronting U.S. policymakers. The rise in the number of illegal immigrants in the United States over the past ten years—from five to twelve million—has led to concerns about the effects of illegal immigration on wages and public finances, as well as the potential security threats posed by unauthorized entry into the country. In the past year alone, the governors of New Mexico and Arizona have declared a “state of emergency” over illegal immigration, and President Bush signed into law the Secure Fence Act, which authorizes the spending of $1.2 billion for the construction of a seven-hundred-mile fence along the U.S.-Mexico border. In this Council Special Report, Professor Gordon H. Hanson of the University of California, San Diego approaches immigration through the lens of economics.
