Decade of Decline in Person Crossings from Mexico and Canada into the United States [open pdf - 461KB]
"The number of persons crossing into the United States through its ports of entry along the Canadian and Mexican borders has been declining since 2000. Recently, research¬ers have proposed various reasons for the decline in per¬son crossings, including (but not limited to) the economies of the three nations and increased security at the borders. This report does not examine reasons for the decline in person crossings, rather the trends in person crossings by mode are investigated. In 2009, there were approximately 252 million person crossings into the United States from Mexico and Canada. The majority of those crossings (75 percent) took place along the Mexican border. Along both the northern and southern borders, a large proportion of crossings were with personal vehicles. An additional 17 percent of total crossings were by pedestrians."
