A new SLC Issue Brief compares historical data from SLC’s various publications to the current position of Southern states’ exports and imports to and from Canada and Mexico. SLC has studied the centrality of the Southern region’s economic integration with Canada and Mexico since the North American Free Trade Agreement (NAFTA) originally was implemented in 1994. After NAFTA’s implementation, the SLC published multiple analyses related to the trade agreement’s impact on the region, including The Influence of the North American Free Trade Agreement on Economic and Social Programs Supported by State Governments in the South; The North American Free Trade Agreement: Changing Economic and Social Programs of Southern States; and NAFTA ’95: A Report Card. The historical context provided by data in SLC’s various publications is essential to understanding the extent to which regional trade has been influenced by NAFTA, and the ways in which it could be impacted if the trade agreement is significantly modified in the months ahead.
