The document analyzes the impact of NAFTA on state-level exports in the United States from 1993 to 2003. It finds that exports to NAFTA partners (Canada and Mexico) grew faster than total US exports over this period, increasing their share. By 2003, NAFTA markets accounted for 37% of US merchandise exports, up from 31% in 1993. Texas was the top exporting state to NAFTA partners in 2003, sending $52.4 billion worth of goods, followed by California at $26.1 billion. Six of the top ten state exporters to NAFTA were traditional manufacturing states in the North.
