The value of U.S. surface transportation trade with Canada and Mexico increased 5.0 percent in May 2012 from April 2012 (Table 2). Month-to-month changes can be affected by seasonal variations and other factors.

U.S. trade by surface transportation with Mexico has increased at a faster pace than trade with Canada. U.S.-Canada and U.S.-Mexico surface transportation trade in May 2012 both increased compared to May 2011 with U.S.-Canada trade reaching $48.1 billion, a 4.0 percent increase, and U.S.-Mexico trade reaching $35.6 billion, a 14.9 percent increase. For trade statistics by mode, see Table 4 for Canada and Table 6 for Mexico.

In May , Michigan led All states in surface trade with Canada, at $6.5 billion, a 2.6 percent increase from May 2011 (Table 5). Of the top 10 states by value, California had the largest percentage increase over May 2011, at 29.7 percent.

The top commodity category transported between the U.S. and Canada by surface modes of transportation in May was vehicles, valued at $9.5 billion (Table 8).

Texas continued to lead All states in surface trade with Mexico at $12.9 billion, a 15.6 percent increase from May 2011. This amount is the highest on record, surpassing the $12.6 billion in Texas Mexico trade in March 2012. Of the top 10 states by value, North Carolina had the biggest percentage increase, 39.1 percent (Table 7), primarily because of a $59 million increase from May 2011 in the export of inorganic chemicals. The top commodity category transported between the U.S. and Mexico by surface modes of transportation in May was electrical machinery with $7.6 billion in trade (Table 9).

Technical Note: The BLS indexes used for Figure 1 adjustment May be revised in each of the three months after original publication. For example, index values released in January 2012 will be subject to revision in February, March and April of that year.
