With respect to the movement of people:

• All indicators show declines in personal travel for every age group, particularly among young people since the early 2000s. It is too soon to tell whether this decline is temporary or indicative of a long-term trend.
• International visitors to the United States rose from a low of 55 million in 2009 to 67 million in 2012, generating $166 billion in export revenue—the highest in this century.
• Carpooling to work has declined since 1980, while driving alone to work has increased. Working exclusively at home has tripled from 2 million in 1980 to over 6 million in 2012.
• Transit use for the trip to work reached a low point in the mid-1990s and has since slowly regained in share. It now accounts for 5 percent of these trips, with higher levels in some metropolitan areas (e.g., New York City, San Francisco, and Washington, DC, being the highest).
• In 2011 about 9 percent of households had no vehicle. However, only 4 percent of households with a worker were without a vehicle, underscoring the critical role the personal vehicle plays in getting employees to and from work.
• In 2013, 9.7 million domestic and international flights arrived at and departed from U.S. airports; 825 million revenue passengers enplaned. Both numbers are below the 2007 peak.
