As a result of the late-2000s recession, international arrivals suffered a strong slowdown beginning in June 2008. Growth from 2007 to 2008 was only 3.7% during the first eight months of 2008. This slowdown on international tourism demand was also reflected in the air transport industry, with a negative growth in September 2008 and a 3.3% growth in passenger traffic through September. The hotel industry also reported a slowdown, with room occupancy declining. In 2009 worldwide tourism arrivals decreased by 3.8%. By the first quarter of 2009, real travel demand in the United States had fallen 6% over six quarters. While this is considerably milder than what occurred after the 9/11 attacks, the decline was at twice the rate as real GDP has fallen.
