A total 5.1 million U.S. citizens traveled abroad in September 2014, up six percent over September 2013, according to monthly statistics released this week by the U.S. National Travel and Tourism Office.

This brings U.S. citizen international travel to 52.1 million in the first eight months of the year.

Every month, the NTTO releases data regarding recent travel activity, including details about outbound travel from the United States. This is the most recent month for which this information is available.

Throughout September, travel to overseas locations accounted for 46 percent of U.S. outbound international travel while a slightly higher percentage, 54 percent, went no farther than Canada or Mexico.

Europe and the Caribbean remain the most popular destinations throughout September capturing a total 29 percent of all travel.

The greatest growth among overseas markets year-over-year was seen in the Middle East, up 20 percent, to 133,000 travelers, and the Caribbean, up 10 percent to 347,000 travelers.

U.S. travel to border nations of Mexico and Canada increased 7 percent compared to September 2013 with the most growth seen in Mexico. American visits to Mexico increased 11 percent to 1.6 million travelers, but only increased one percent to 1.2million people in Canada.
